Abstract

Extracts of post-exponential phase mycelia of Streptomyces bikiniensis ATCC 11062, and other streptomycin-producers, catalyze phosphorylation of streptomycin and dihydrostreptomycin with adenosine-5'-triphosphate. The phosphate is esterified with an -OH group of the streptidine moiety. It is suggested that O-phosphoryl-streptomycin might serve as an intracellular precursor of extracellular streptomycin or as a detoxification product of streptomycin or that it might serve an unknown physiological function in the producing organism.

摘要

比基尼链霉菌ATCC 11062及其他链霉素产生菌指数生长期后菌丝体的提取物,可催化链霉素和二氢链霉素与三磷酸腺苷发生磷酸化反应。磷酸酯与链霉胍部分的一个-OH基团酯化。有人提出,O-磷酰基链霉素可能作为细胞外链霉素的细胞内前体,或作为链霉素的解毒产物,或者它可能在产生菌中发挥未知的生理功能。
