- * Glyoxalase I signatures *
- ***************************
-
- Glyoxalase I (EC 4.4.1.5) (lactoylglutathione lyase) catalyzes the first step
- of the glyoxal pathway, the transformation of methylglyoxal and glutathione
- into S-lactoylglutathione which is then converted by glyoxalase II to lactic
- acid [1]. Glyoxalase I is an ubiquitous enzyme which binds one mole of zinc
- per subunit. The bacterial and yeast enzymes are monomeric while the mammalian
- one is homodimieric.
-
- The sequence of Pseudomonas putida glyoxalase I is highly similar to that of
- the human enzyme. We have derived two signature patterns for this enzyme. Both
- patterns are located in the central section of the protein and contain one or
- two conserved histidines that could be implicated in the binding of the zinc
- atom.
-
- -Consensus pattern: L-E-L-T-H-N-x-G-T-E
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
-
- -Consensus pattern: Y-H-[ND]-G-N-[ST]-D-P-R-G-F-G-H
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
