O-acetylserine sulfhydrylase A (CysK) is the pyridoxal 5'-phosphate-dependent enzyme that catalyzes the final reaction of cysteine biosynthesis in bacteria. CysK was initially identified in a complex with serine acetyltransferase (CysE), which catalyzes the penultimate reaction in the synthetic path

The O-acetylation of the essential cell wall polymer peptidoglycan is essential in many bacteria for their integrity and survival, and it is catalyzed by peptidoglycan O-acetlytransferase B (PatB). Using PatB from Neisseria gonorrhoeae as the model, we have shown previously that the enzyme has speci

Serine acetyltransferase (CysE) is involved in L-cysteine biosynthesis in Mycobacterium, and it is important for the self-defense mechanism of the bacteria. Mycobacterium tuberculosis CysE (Rv2335) has been identified as a serine acetyltransferase, and it is orthologous to Mycobacterium smegmatis MS
