Gene

GLO5

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Caution

Catalytic activityi

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

Cofactori

FMNPROSITE-ProRule annotation

Pathwayi: photorespiration

This protein is involved in step 2 of the subpathway that synthesizes glycine from 2-phosphoglycolate.
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. no protein annotated in this organism
  2. Peroxisomal (S)-2-hydroxy-acid oxidase GLO5 (GLO5), (S)-2-hydroxy-acid oxidase GLO2 (GLO2), Peroxisomal (S)-2-hydroxy-acid oxidase GLO3 (GLO3), (S)-2-hydroxy-acid oxidase GLO1 (GLO1), Peroxisomal (S)-2-hydroxy-acid oxidase GLO4 (GLO4)
  3. no protein annotated in this organism
This subpathway is part of the pathway photorespiration, which is itself part of Photosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes glycine from 2-phosphoglycolate, the pathway photorespiration and in Photosynthesis.
