Glutaminase, Recombinant, E. coli, aa1-310, His-tag

Glutaminase belongs to the large superfamily of serine-dependent beta-lactamases and penicillin-binding proteins. They are present in most bacteria and eukaryotes and catalyze the hydrolytic deamidation of l-glutamine to l-glutamate and free NH4+. Source: Recombinant corresponding to aa1-310 glsA1, fused to His-tag at N-terminus expressed in E. coli.
