Protein

NADP-dependent malic enzyme, chloroplastic

Gene

ME6

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

Functioni

The chloroplastic ME isoform decarboxylates malate shuttled from neighboring mesophyll cells. The CO2 released is then refixed by ribulose-bisphosphate carboxylase. This pathway eliminates the photorespiratory loss of CO2 that occurs in most plants.

Catalytic activityi

(S)-malate + NADP+ = pyruvate + CO2 + NADPH.
Oxaloacetate = pyruvate + CO2.

Cofactori

Mg2+By similarity, Mn2+By similarityNote: Divalent metal cations. Prefers magnesium or manganese.By similarity

Pathwayi: C4 acid pathway

This protein is involved in the pathway C4 acid pathway, which is part of Photosynthesis.
View all proteins of this organism that are known to be involved in the pathway C4 acid pathway and in Photosynthesis.

Similar proteinsi

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.
