Protein

Membrane-bound lytic murein transglycosylase F 1

Gene

mltF1

Organism
Alkalilimnicola ehrlichii (strain ATCC BAA-1101 / DSM 17681 / MLHE-1)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Murein-degrading enzyme that degrades murein glycan strands and insoluble, high-molecular weight murein sacculi, with the concomitant formation of a 1,6-anhydromuramoyl product. Lytic transglycosylases (LTs) play an integral role in the metabolism of the peptidoglycan (PG) sacculus. Their lytic action creates space within the PG sacculus to allow for its expansion as well as for the insertion of various structures such as secretion systems and flagella.UniRule annotation

Catalytic activityi

Exolytic cleavage of the (1->4)-beta-glycosidic linkage between N-acetylmuramic acid (MurNAc) and N-acetylglucosamine (GlcNAc) residues in peptidoglycan, from either the reducing or the non-reducing ends of the peptidoglycan chains, with concomitant formation of a 1,6-anhydrobond in the MurNAc residue.UniRule annotation

Domaini

The N-terminal domain does not have lytic activity and probably modulates enzymatic activity. The C-terminal domain is the catalytic active domain.UniRule annotation

Sequence similaritiesi

In the N-terminal section; belongs to the bacterial solute-binding protein 3 family.UniRule annotation
In the C-terminal section; belongs to the transglycosylase Slt family.UniRule annotation
