Protein

Hydroxyacylglutathione hydrolase, mitochondrial

Gene

HAGH

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Thiolesterase that catalyzes the hydrolysis of S-D-lactoyl-glutathione to form glutathione and D-lactic acid.

Caution

Only one single gene encoding glyoxalase II has been identified in vertebrates. In yeast and higher plants, separate genes encode the cytosolic and mitochondrial forms of glyoxalase II.1 Publication

Catalytic activityi

S-(2-hydroxyacyl)glutathione + H2O = glutathione + a 2-hydroxy carboxylate.

Cofactori

Zn2+1 PublicationNote: Binds 2 Zn2+ ions per subunit.1 Publication

Pathwayi: methylglyoxal degradation

This protein is involved in step 2 of the subpathway that synthesizes (R)-lactate from methylglyoxal.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Lactoylglutathione lyase (HEL-S-74), Lactoylglutathione lyase (GLO1), Lactoylglutathione lyase (GLO1)
  2. Hydroxyacylglutathione hydrolase, mitochondrial (HAGH)
This subpathway is part of the pathway methylglyoxal degradation, which is itself part of Secondary metabolite metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes (R)-lactate from methylglyoxal, the pathway methylglyoxal degradation and in Secondary metabolite metabolism.
