Notes

[back to top]


MtgA has flavomycin-resistant peptidoglycan synthesis activity (Di Berardino, 1996 [5]; Derouaux, 2007). mtgA is a non-essential gene (Schiffer, 1999). MtgA localizes to the division site and interacts with FtsW, FtsN, and FtsI in mcrA(Ts) mrcB- strains, indicating a role for MtgA in peptidoglycan synthesis related to the cell cycle (Derouaux, 2007). The use of the term transglycolase is ambiguous as it can describe both lytic and synthetic peptidoglycan activities, therefore glycosyltransferase is preferred (Di Berardino, 1996). MtgA lacks a penicillin binding domain and therefore is penicillin-insensitive. MtgA is a membrane-bound periplasmic enzyme that has an uncleaved signal anchor (Di Berardino, 1996). MtgA may be the glycan polymerase characterized by Hara (1984), although it has an apparent MW larger than MtgA (Di Berardino, 1996).[4]
