General annotation (Comments)

Function

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.

Catalytic activity

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

Cofactor

FMN By similarity.

Pathway

Photosynthesis; photorespiration; glycine from 2-phosphoglycolate: step 2/3.

Subunit structure

Homotetramer or homooctamer. Interacts with rice dwarf virus (RDV) P8. This interaction promotes viral P8 relocation to virus factories peripheral to peroxisomes By similarity.

Subcellular location

Peroxisome By similarity.

Sequence similarities

Belongs to the FMN-dependent alpha-hydroxy acid dehydrogenase family.

Contains 1 FMN hydroxy acid dehydrogenase domain.

Sequence caution

The sequence EEC82445.1 differs from that shown. Reason: Erroneous gene model prediction.
