The specificity of action of the lysosomal elastase of human neutrophil leucocytes on the oxidized B chain of insulin is similar to that of pig pancreatic elastase, but is more directed towards valine than alanine as the residue contributing the carboxyl group of the cleaved bond. The most susceptible bonds are Val-12-Glu-13 and Val-18-Cys(O3H)-19. Other bonds hydrolysed are Ala-14-Leu-15, Ser-9-His-10 and Cys, (O3H3)-7-Gly-8. Tables listing amino acid composition, N-terminal residue, and yields of isolated peptides have been deposited as Supplementary Publication SUP 50 075 (8 pages) at the British Library Lending Division, Boston Spa, Wetherby, West Yorkshire LS23 7BQ, U.K., from whom copies can be obtained on the terms indicated in Biochem.

人中性粒细胞溶酶体弹性蛋白酶对胰岛素氧化B链的作用特异性与猪胰弹性蛋白酶相似,但在作为裂解键羧基供体残基方面,对缬氨酸的作用比对丙氨酸更强。最敏感的键是Val-12-Glu-13和Val-18-Cys(O3H)-19。其他被水解的键是Ala-14-Leu-15、Ser-9-His-10和Cys,(O3H3)-7-Gly-8。列出氨基酸组成、N端残基和分离肽产量的表格已作为补充出版物SUP 50 075(8页)存放在英国西约克郡韦瑟比波士顿温泉市英国国家图书馆文献供应处,邮编LS23 7BQ,可按《生物化学杂志》(1977年)161, 1中所示条件从该处获取复印件。
