Abstract excerpt

Structural-based mutational analysis of salt-tolerant glutaminase from Micrococcus luteus K-3 (Micrococcus glutaminase) revealed that three amino acid residues, S64, K67, and E160, were essential to a catalytic reaction. The result suggested that Micrococcus glutaminase had a possible catalytic mechanism similar to class A beta-lactamase rather than glutaminase-asparaginase from Pseudomonas 7A.
