Notizen: [Auszug] WHEN an alkaline extract of yeast is saturated with ammonium sulphate there is precipitated, with the protein, cytochrome ‘C’ and a complex iron compound giving no visible spectrum. The latter can be separated from the proteins slowly by ultra-filtration. It remains in solution when the ...

Notizen: [Auszug] AUTOIMMUNITY is a rare event despite the genetic potential of every individual to mount immune responses to autologous antigens. This is due to the fact that the immune system somehow 'learns' to recognize these antigens as self and to tolerate them1. The way in which self tolerance occurs is ...

Notizen: [Auszug] THE suggestion by Keeley et al\ supported by Moore2, that Stylites may represent an important link between aquatic plants and primitive land plants has little foundation in fact. To go further and propose that these plants could be relics of a marginally successful compromise from which present-day ...

Notizen: [Auszug] The effects of amino-acid replacements on the disulphide-coupled folding pathway of bovine pancreatic trypsin inhibitor have been examined. Replacements at three sites destabilize the native protein relative to the unfolded state, but have different effects on the relative stabilities of the ...

Notizen: [Auszug] It appeared probable to us that the source of the confusion was the chemical identity of the ethylene-is-(trimethylammonium) tested. In particular, the reaction of ethylene bromide with trimethylamine has long been known6 to produce a mixture of salt products. Moreover, neither Barlow and Ing1 nor ...

Notizen: [Auszug] That the latter explanation is the most likely is suggested by recent reports of the darkening of hair colour in patients with phenylketonuria who were maintained on synthetic diets deficient in phenylalanine2-4. The blonde colour may, therefore, result from the reversible inhibition of tyrosinase ...

Notizen: [Auszug] The amino-acid sequence of the precursor of the human tumour cell line-derived platelet-derived growth factor (PDGF) A-chain has been deduced from complementary DNA clones and the gene localized to chromosome 7. The protein shows extensive homology to the PDGF B-chain precursor. Expression of the ...
