Lactamase_B

Lactamase_B
PFAM accession number:PF00753
Interpro abstract (IPR001279): Apart from the beta-lactamases and metallo-beta-lactamases, a number of other proteins contain this domain [(PUBMED:7588620)]. These proteins include thiolesterases, members of the glyoxalase II family, that catalyse the hydrolysis of S-D-lactoyl-glutathione to form glutathione and D-lactic acid and a competence protein that is essential for natural transformation in Neisseria gonorrhoeae and could be a transporter involved in DNA uptake. Except for the competence protein these proteins bind two zinc ions per molecule as cofactor.

This is a PFAM domain. For full annotation and more information, please see the PFAM entry Lactamase_B
