Abstract
Cyanophycin granule polypeptide content increased by 2- to 3-fold, soluble protein content decreased by 1.5-fold, and carbohydrate content increased by 2-fold within 6 h of chloramphenicol addition to exponentially growing cells of Aphanocapsa sp. strain 6308. Analysis of 14C- and 3H-labeled cells transferred to unlabeled medium and analysis of pulse-labeled cells both suggested cyanophycin granule synthesis from preformed protein breakdown.
摘要
在向指数生长的聚球藻属6308菌株细胞中添加氯霉素后的6小时内，藻青素颗粒多肽含量增加了2至3倍，可溶性蛋白质含量降低了1.5倍，碳水化合物含量增加了2倍。对转移至未标记培养基中的14C和3H标记细胞的分析以及对脉冲标记细胞的分析均表明，藻青素颗粒是由预先形成的蛋白质分解合成的。
