Protein

Pyruvate dehydrogenase [NADP(+)]

Gene

PFOR

Organism
Cryptosporidium parvum
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at transcript leveli

Functioni

May have an important role in respiratory metabolism. Cryptosporidium have a relic mitochondrion with no function in energy metabolism so it is not known if PFOR has a function.1 Publication

Miscellaneous

Arose from gene fusion of pyruvate:ferredoxin oxidoreductase and cytochrome-P450 reductase. Gene fusion has only been found in Euglena and Cryptosporidium.1 Publication

Catalytic activityi

Pyruvate + CoA + NADP+ = acetyl-CoA + CO2 + NADPH.1 Publication

Cofactori

Protein has several cofactor binding sites:

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.
