Chains	Enzyme Name	Description	Catalytic Residues
A	glutaminase M-CSA #301	Glutaminases (EC:3.5.1.2) deaminate glutamine to glutamate. In Bacillus subtilis, glutaminase is encoded by glnA, which is part of an operon, glnA-glnT (formerly ybgJ-ybgH), where glnT encodes a glutamine transporter. The glnA-glnT operon is regulated by the 2-component system GlnK-GlnL in response to glutamine [PMID:15995196].
