    Notes: A variety of human haemoglobins (Hbs) are produced at different stages of human development, including three embryonic Hbs, foetal Hb and adult Hb. All are heterotetramers. During crystallization experiments on human embryonic Hb Portland (ζ2γ2), it was discovered by crystallographic and biochemical analysis that the homotetramer Hb Bart's (γ4) preferentially crystallizes from ζ2γ2 solutions below pH 5. This results from dissociation of Hb Portland into γ2 dimers and ζ monomers and has interesting implications for subunit interactions and tetramer stability in Hbs. It also makes possible a full crystallographic analysis of Hb Bart's, which is of considerable medical significance because of its presence in the red blood cells of millions of people worldwide who suffer from α-thalassaemia.

    Notes: Human bile-salt dependent lipase (BSDL), secreted into both the digestive tract and human milk, is integral to the effective absorption of dietary lipids. In attempts to obtain crystals suitable for high-resolution X-ray crystallographic studies, various forms of the enzyme have been crystallized, including native and desialidated human milk BSDL and both intact recombinant BSDL and a truncated form lacking the heavily glycosylated C-terminal repeat region. Trigonal crystals of native BSDL, with unit-cell parameters a = b = 90.0, c = 156.1 Å, were obtained using 15–20%(w/v) PEG 8000 as precipitant. These crystals diffract to 3.5 Å along the unique axis, but to only 5–7 Å in orthogonal directions. Crystals of recombinant truncated BSDL grown from 15–20%(w/v) PEG 6000 are orthorhombic, space group P212121, with unit-cell parameters a = 59.2, b = 90.0, c = 107.7 Å, and diffract to 2.6 Å resolution. These are suitable for structural analysis by X-ray crystallography.

    Notes: Methylmalonyl-CoA epimerase (MMCE) is an enzyme that interconverts the R and S epimers of methylmalonyl-CoA in the pathway that links propionyl-CoA with succinyl-CoA. This is used for both biosynthetic and degradative processes, including the breakdown of odd-numbered fatty acids and some amino acids. The enzyme has been expressed in Escherichia coli both as the native enzyme and as its selenomethionine (SeMet) derivative. Crystals of both forms have been obtained by vapour diffusion using monomethylether PEG 2000 as precipitant. The native MMCE crystals are orthorhombic, with unit-cell parameters a = 56.0, b = 114.0, c = 156.0 Å, and the SeMet-MMCE crystals are monoclinic, with unit-cell parameters a = 43.6, b = 78.6, c = 89.4 Å, β = 92.0°; both diffract to better than 2.8 Å resolution.

    Description: Soil profiles were collected along a transect across the Serengeti ecosystem, in Tanzania from 2-3S and 34-35.5E, 1153 to 1677 m above sea level and 0 to 1.6 m soil depth. The samples are modern soils and the temporal span of the soil depth profiles is unconstrained, likely centuries to millennia. The survey is intended to observe soil microbial lipid biomarkers that are commonly used as proxies for temperature and pH and to assess their robustness in alkaline carbonate-precipitating soil profiles, where soil carbonate proxies can also be applied. These modern calibrations can inform reconstructions of Eastern African paleoenvironments using the same proxies in geological archives. Lipid extractions and purifications were performed at USC in 2018-2019 and abundances of branched and isoprenoidal glycerol dialkyl glycerol tetraethers were obtained by high pressure liquid chromatography mass spectrometry, performed in 2020-2021 at the University of Arizona. Contextual data include total dissolved solids and pH measurements at the University of Houston in 2020-2021. For more information, please consult associated manuscript on the GDGTs within these soil profiles: Peaple et al., (2022) Identifying the drivers of GDGT distributions in alkaline soil profiles within the Serengeti ecosystem, Organic Geochemistry, in review.

That study includes stable hydrogen isotopic data on plant wax, available from doi:10.1594/PANGAEA.921002.

    Description: Size segregated aerosol samples were collected during the OASIS (“Organic very short lived substances and their Air Sea Exchange from the Indian Ocean to the Stratosphere”) cruises (FS Sonne, SO234-2 & SO235) during 8 - 20 July & 23 July – 7 August 2014 in the southern Indian Ocean (~30 E - 75 E, 30 S – 5 N). The samples were collected by Birgit Quack of GEOMAR, Kiel, Germany. The aerosol sampler was situated on the roof of the ship's wheelhouse and was connected to an automatic wind sector controller to prevent contamination of the samples from the ship's stack. Most samples were collected using a Sierra-type cascade impactor to separate the aerosol particles at an aerodynamic diameter cutoff of 1 µm. Collection time for these samples varied between 27.7 and 46.9 hours. For one sample, 6 impactor stages and a backup filter were used to give more detailed information aerosol size distribution. This sample was collected over 91.7 hours. Samples were extracted with ultrapure water and the major ions Na+, NH4+, Mg2+, K+, Ca2+, Cl-, NO3-, SO42-, oxalate, Br- and methanesulfonate were determined by ion chromatography (IC). Total soluble iodine (TSI) was determined by inductively coupled plasma - mass spectrometry (ICP-MS) and iodide (I-) and iodate (IO3-) were determined by IC-ICP-MS. The dataset contains the atmospheric concentrations of all measured soluble major ions (in nmol/m³) and iodine species (in pmol/ m³).

    Description: Size segregated aerosol samples were collected during the M138 cruise (FS Meteor) during 6 June - 1 July 2017 in the eastern Pacific Ocean (~86 W - 76 W, 16 S – 5 N). The samples were collected by Hermann Bange of GEOMAR, Kiel, Germany. The aerosol sampler was situated on the roof of the ship's wheelhouse and its operation was controlled by an automatic wind sector controller to prevent contamination from the ship's stack. Samples were collected using a Sierra-type cascade impactor to separate the aerosol particles at an aerodynamic diameter cutoff of 1 µm. Collection time for these samples varied between 14.3 and 65.2 hours. Samples were extracted with ultrapure water and the major ions Na+, NH4+, Mg2+, K+, Ca2+, Cl-, NO3-, SO42-, oxalate, Br- and methanesulfonate were determined by ion chromatography (IC). Total soluble iodine (TSI) was determined by inductively coupled plasma - mass spectrometry (ICP-MS) and iodide (I-) and iodate (IO3-) were determined by IC-ICP-MS. Analysis work was performed by Andrew Smith of University of East Anglia, Norwich, UK. The dataset contains the atmospheric concentrations of all measured soluble major ions (in nmol/m³)) and iodine species (in in pmol/m³). The data are reported in “Soluble iodine speciation in marine aerosols across the Indian and Pacific Ocean basins”, E. Droste et al., Frontiers in Marine Science, in preparation, (2021).
