Function

Toxic component of a type II toxin-antitoxin (TA) system. Phosphorylates UDP-N-acetyl-D-glucosamine (UNAG) on the 3'-hydroxyl group of the N-acetyl-D-glucosamine moiety, yielding UNAG-3P. UNAG-3P inhibits MurA, the first committed step in cell wall synthesis, which is then blocked.

Product Specifications

Recombinant Streptococcus agalactiae Toxin zeta is a recombinant protein from Streptococcus agalactiae, expressed in Yeast, covering amino acids 1-287aa, with N-terminal 6xHis-tagged tag, molecular weight 34.7kDa, purity Greater than 90% as determined by SDS-PAGE..

Function

Toxic component of a type II toxin-antitoxin (TA) system. Phosphorylates UDP-N-acetyl-D-glucosamine (UNAG) on the 3'-hydroxyl group of the N-acetyl-D-glucosamine moiety, yielding UNAG-3P. UNAG-3P inhibits MurA, the first committed step in cell wall synthesis, which is then blocked. Phosphorylation is inhibited by cognate epsilon antitoxin. Part of a postsegregational killing (PSK) system involved in the killing of plasmid-free cells. The zeta toxin induces programmed cell death (By similarity)

Subunit

In the presence of the epsilon antitoxin, forms an inactive PezA(2)PezT(2) heterotetramer

Organism: Streptococcus agalactiae  |  Synonyms: UDP-N-acetylglucosamine kinase
