Abstract
For disintegration of chicken feathers by Streptomyces pactum, keratinolytic proteinases and extracellular reduction of disulfide bonds were necessary. Conditions for disulfide reduction were examined with oxidized glutathione as model substrate. The reduction of glutathione depended on the presence of metabolically active cells. The mycelium also reduced tetrazolium dyes and cystine.
摘要
为了使链霉菌分解鸡毛，角蛋白水解酶和细胞外的二硫键还原是必要的。用氧化型谷胱甘肽作为模型底物研究了二硫键还原的条件。还原型谷胱甘肽的形成依赖于具有代谢活性的细胞的存在。菌丝体还能还原四唑染料和胱氨酸。
