    Interaction of Ca2+ and H+ with heme A in cytochrome oxidase (1980)

    Notes: Abstract Ca2+ ions shift the absorption spectrum of reduced cytochromea in mitochondria by acting from the outside of the membrane. In isolated cytochrome oxidase the shift may be induced by either Ca2+ or H+, the apparent pK varying between 6.20 and 5.75 depending on the state of cytochromea 3. Studies of the Soret band show that Ca2+ also shifts the spectrum of ferrocytochromea 3 in isolated oxidase in contrast to the situation in mitochondria or isolated oxidase reconstituted into liposomes. Model studies with reduced bis-imidazole heme A reveals an analogous spectral shift induced by Ca2+. Esterification of the propionate carboxyls of heme A abolishes the spectral shift, suggesting that it is due to interaction of Ca2+ with these groups. When taken together with the data with intact mitochondria, this suggests that the propionate side chains of cytochromea are accessible to Ca2+ and H+ from the outside of the mitochondrial membrane. In the soluble enzyme both hemesa anda 3 are accessible. Thus hemea may be located near the outside of the inner membrane whereas hemea 3 experiences a different environment in which no Ca2+ shift occurs.

    Notes: Abstract Polyclonal rabbit antibodies against a Ca2+-binding mitochondrial glycoprotein were found to inhibit the uniporter-mediated transport of Ca2+ in mitoplasts prepared from rat liver mitochondria. Spermine, a modulator of the uniporter, decreased the inhibition. This glycoprotein ofM r 40,000, isolated from beef heart mitochondria and earlier shown to form Ca2+-conducting channels in black-lipid membranes, thus is a good candidate for being a component of the uniporter. Antibody-IgG was found to specifically bind to mitochondria in human fibroblasts.

    Fine-root biomass, fine-root production and environmental variables in four forested site types under undrained and drained conditions in Lakkasuo peatland, Southern Finland (2023)
    PANGAEA
    Details
    Publication Date: 2023-05-10
    Description: We estimated fine-root biomass (FRB) and production (FRP) and their depth distribution and plant functional type (PFT) composition in four forested boreal peatland site types that varied in soil nutrient and water-table level regimes, ground vegetation and tree stand characteristics. Two were pine-dominated nutrient-poor sites (dwarf-shrub pine bog, tall-sedge pine fen) and two spruce-dominated nutrient-rich sites (Vaccinium myrtillus spruce swamp, herb-rich hardwood-spruce swamp). Measurements were done in two sites per site type: one undrained site and one site that had been drained for forestry. In each of the eight sites, we established three measurement plots. FRB was estimated by separating and visually identifying roots from soil cores extending down to 50-cm depth. The cores were taken in late August, 2016. FRP was estimated using ingrowth cores covering the same depth, and the separated roots were identified using Fourier transform infrared spectroscopy (FTIR). The ingrowth cores were incubated for two years, starting in November 2015 and ending in November 2017. Tree-stand basal area and stem volume per species, and projection cover of ground vegetation per species were determined in summer 2018. We monitored the soil water-table level and soil temperatures in 5 and 30 cm depths with dataloggers. Soil pH, bulk density, and carbon, nitrogen, phosphorus, potassium, calcium, magnesium, iron, manganese, boron, zinc, and copper concentrations were measured from peat cores extending down to 50-cm depth and taken simultaneously with the FRB cores. FRB, FRP and peat properties are presented for 10-cm depth segments. FRB, FRP and peat properties are presented for 10-cm depth segments. Peat cores were taken with a box-shaped 65 mm x 37 mm peat corer, except in the wet TP site where a 60 mm x 60 mm corer was used.

    Description: Peat cores were taken in late August, 2016, with a box-shaped 65 mm x 37 mm peat corer, except in the wet TP site where a 60 mm x 60 mm corer was used. One core per plot = three cores per site were taken. The cores were divided into 10-cm segments from soil surface to 50 cm depth. Peat pH and bulk density were determined for each segment. For nutrient analyses, the segments representing the same depths from the 3 cores per site were combined and homogenized by milling. Drying temperature was 70 °C, and the dry matter content was estimated with a subsample dried at 105 °C.
