Cryo-EM structure of T7 bacteriophage DNA translocation gp15-gp16 core complex intermediate assembly

Released:

Function and Biology Details

Reaction catalysed:
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.
