Organism
Escherichia coli str. K-12 substr. MG1655 (strain: K-12, substrain: MG1655)
Lineage
Bacteria; Pseudomonadati; Pseudomonadota; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia
Also known as
ECK0479; ybaS
Summary
Two glutaminases have been purified and biochemically characterized from Escherichia coli B. ybaS might contribute to acid resistance (Brown, 2008). [More information is available at EcoGene: EG13247]. YbaS is a glutaminase that is highly selective for L-glutamine. [More information is available at EcoCyc: G6261].
