Production, purification, and characterization of an extracellular chitosanase from Streptomyces [PDF]

open access: yesJournal of Bacteriology, 1975
The synthesis by Streptomyces sp. no. 6 of an extracellular chitosanase was induced by glucosamine. The enzyme was purified to homogeneity by Sephadex G-100, carboxymethyl-cellulose, and diethylaminoethyl-cellulose chromatography. The purified enzyme hydrolyzed chitosan (the beta-1,4-linked polymer of glucosamine) but not chitin nor carboxymethyl ...

N‐acetylglucosamine sensing in the filamentous soil fungus Trichoderma reesei

open access: yesThe FEBS Journal, Volume 292, Issue 12, Page 3072-3090, June 2025.
N‐acetylglucosamine (GlcNAc) is involved in diverse signaling pathways in dimorphic yeasts and bacteria, including virulence and cell death. Here, we investigated GlcNAc sensing in Trichoderma reesei. GlcNAc signaling influences around 2100 genes in this filamentous soil fungus.
