Gene

GLO4

Organism
Oryza sativa subsp. japonica (Rice)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at transcript leveli

Functioni

Photorespiratory enzyme that can exert a strong regulation over photosynthesis, possibly through a feed-back inhibition on Rubisco activase. Not required for oxalate accumulation (By similarity).By similarity

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 GLO4 (GLO4), Peroxisomal (S)-2-hydroxy-acid oxidase GLO1 (GLO1), Peroxisomal (S)-2-hydroxy-acid oxidase GLO5 (GLO5), Peroxisomal (S)-2-hydroxy-acid oxidase GLO2 (GLO2), Peroxisomal (S)-2-hydroxy-acid oxidase GLO3 (GLO3)
  3. no protein annotated in this organism
This subpathway is part of the pathway photorespiration, which is itself part of Photosynthesis.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
