protein-phosphocysteine-sugar phosphotransferase activity protein-phosphocysteine-N-acetylglucosamine phosphotransferase system transporter activity tb molecular_function 2014-06-04T16:22:31Z GO:0090586 Catalysis of the PEP-dependent, phosphoryl transfer-driven transport of substances across a membrane. The transport happens by catalysis of the reaction: protein S-phosphocysteine + N-acetylglucosamine (out) = protein cysteine + N-acetylglucosamine-6-phosphate (in).
