Reduction of Disulfide Bonds by Streptomyces pactum during Growth on Chicken Feathers
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.

Protein Modifications in the RER
Broadly, these modifications can be categorized into four main categories — glycosylation, formation of disulfide bonds, assembly of protein subunits, and specific proteolytic cleavages like removal of signal sequences.
