Protein

Hydroxyacid oxidase 1

Gene

HAO1

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Has 2-hydroxyacid oxidase activity. Most active on the 2-carbon substrate glycolate, but is also active on 2-hydroxy fatty acids, with high activity towards 2-hydroxy palmitate and 2-hydroxy octanoate.1 Publication

Catalytic activityi

(S)-2-hydroxy acid + O2 = 2-oxo acid + H2O2.1 Publication

Cofactori

FMNPROSITE-ProRule annotation1 Publication

Kineticsi

  1. KM=141 µM for glycolate1 Publication
  2. KM=40 µM for 2-hydroxy octanoate1 Publication
  3. KM=2200 µM for glyoxylate1 Publication

    Pathwayi: glycolate degradation

    This protein is involved in step 1 of the subpathway that synthesizes 3-phospho-D-glycerate from glycolate.
    Proteins known to be involved in the 4 steps of the subpathway in this organism are:
    1. Hydroxyacid oxidase 1 (HAO1)
    2. no protein annotated in this organism
    3. no protein annotated in this organism
    4. no protein annotated in this organism
    This subpathway is part of the pathway glycolate degradation, which is itself part of Organic acid metabolism.
    View all proteins of this organism that are known to be involved in the subpathway that synthesizes 3-phospho-D-glycerate from glycolate, the pathway glycolate degradation and in Organic acid metabolism.
