MraY family signatures





Description

Phospho-N-acetylmuramoyl-pentapeptide-transferase (EC 2.7.8.13) (mraY) [1] is a bacterial enzyme responsible for the formation of the first lipid intermediate of the cell wall peptidoglycan synthesis. It catalyzes the formation of undecaprenyl-pyrophosphoryl-N-acetylmuramoyl-pentapeptide from UDP-MurNAc-pentapeptide and undecaprenyl-phosphate.

It is an integral membrane protein with probably ten transmembrane domains. It belongs to family 4 of glycosyl transferases. Homologs of mraY have been found in the archaebacteria Methanobacterium thermoautotrophicum and in Arabidopsis thaliana.

We developed two patterns for this family of enzyme. The first one is located at the end of the first cytoplasmic loop and the beginning of the second transmembrane domain. The second pattern is located in the third cytoplasmic loop.
