Also known as
ECK2696; slt
Summary
MltB cleaves the glycosidic bonds between the N-acetylmuramic acid and N-acetylglucosamine residues in murein. [More information is available at EcoGene: EG12699]. MltB is one of six (along with MltA, MltC, MltD, EmtA, and Slt70) major lytic endotransglycosylases expressed in Escherichia coli. [More information is available at EcoCyc: G7410].
