Lactamase_B

Metallo-beta-lactamase superfamily
Lactamase_B
SMART accession number:SM00849
Description: Apart from the 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.
