additional information the microbial enzyme specifically catalyzes deamidation of proteins without protein hydrolysis pretreatment and only reacts with glutamine residues in the side-chains of proteins or long peptides. Strain QSH1265 can produce acid from D-glucose, maltose, L-arabinose, sucrose, glycerol, and mannitol but not fructose, and it is also positive for indole production and urease activity Chryseobacterium proteolyticum ?
