| malfunction | absence of this enzyme impairs the growth of Listeria under mild acidic conditions at pH 4.8 and reduced its survival in synthetic human gastric fluid at pH 2.5, corresponding to a loss in ammonia production | Listeria monocytogenes |
| metabolism | catabolic ornithine and putrescine carbamoyltransfer reactions constitute the second step of arginine deiminase and agmatine deiminase pathways. However, the equilibrium of in vitro carbamoyltransfer reactions is overwhelmingly towards the anabolic direction, suggesting that catabolic carbamoyltransferase is probably the limiting step of the pathways. lmo0036 is induced at the transcriptional level when Listeria monocytogenes is subjected to low-pH stress. Its expression product in Escherichia coli exhibits higher catabolic carbamoyltransfer activities under acidic conditions | Listeria monocytogenes |
| physiological function | Lmo0036 is responsible for acid tolerance at both sublethal and lethal pH levels and plays a possible role in Listeria virulence | Listeria monocytogenes |
