The synthesis of the sequence 71-86 (XIII) of human proinsulin (sequence 6-21 of human insulin-A-chain) via the fragments 71-78 (XIy1,3) and 79-86 (XII) is described. The good solubility of the protected peptide derivatives belonging to the sequences 75-78 (IXx1,2), 79-86 (X), and 71-78 (XIy1,2), and of the fragment 71-86 (XIII) itself in organic solvents allows a quick and efficient purification of these derivatives by liquid chromatography on silica-gel columns. 相似文献

The synthetic Des-1-glycine-A-chain of sheep insulin as the monomeric cyclic bisdisulfide and native bovine B-chain bissulfonate were reduced together with mercaptoethanol. They combined at pH 10.6 to yield Des-A1-glycine-insulin. This was purified by gel and ion exchange chromatography. The low insulin activity (0.4 - 0.6%) as measured by the fat cell test as well as the change in the CD spectrum indicated that the loss of the N-terminal glycine of the A-chain results in fully inactive insulin. This confirms the results obtained earlier by partial synthesis of Des-A1-glycine-insulin. 相似文献

Phakopsora allophyli (Basidiomycota, Uredinales) is described on the basis of the type specimen of Uredo allophili Henn. on Allophylus sp. (Sapindaceae) from Tanzania. The species has paraphysate telia and teliospores with a single papillate germ pore. These
features are unusual for members of the genus Phakopsora. The generic affiliation of the fungus with Phakopsora is discussed. 相似文献

Crosslinking of protein molecules with bifunctional reagents and subsequent electrophoresis of the modified proteins revealed the presence of cytochrome P-450 LM 2 oligomers in proteoliposome membranes obtained in different ways and differing in their phospholipid composition. Data from a comparative analysis of cytochrome P-450 oligomeric structures in solution and in membrane are suggestive of the hexameric organization of cytochrome P-450 LM 2 within proteoliposome membranes. 相似文献

Uredo behnickiana (syn. Hemileia americana and H. oncidii) is known on orchids of the genera Cattleya, Epidendrum, Laelia, Lophiaris and Oncidium. Previously, only the uredinial stages of these fungi have been described. The telial stage of the rust species was found
for the first time on Oncidium marshallianum. Because of a unique combination of morphological characters the fungus could not be assigned to Hemileia or any other known rust genus. Desmosorus is proposed, therefore, as a new genus with Desmosorus oncidii as the single known species. Desmosorus is characterised by (1) suprastomatal sori on which the spores are formed at the ends of branched hyphae, by (2) subglobose
to ovoid, echinulate urediniospores with a smooth patch around the hilum and by (3) thin-walled, oblong elliptical to cylindrical
teliospores with a rounded apex. 相似文献
