GlycosylTransferase Family 51

Activities in Familymurein polymerase (EC 2.4.1.129).
Mechanism Inverting
3D Structure Statuslysozyme-type
Catalytic Nucleophile/BaseGlu
NoteThere are two categories of enzymes in this family : monofunctional (just the GT51 module) or bifunctional (GT51 module attached to a penicillin-binding transpeptidase module). These enzymes utilise Und-PP-MurAc-(GlcNAc)-pentapeptide as the sugar donor.
