Protein
2-methyl-aconitate isomerase
Organism
Shewanella oneidensis (strain MR-1)
Function
Involved in the catabolism of short chain fatty acids (SCFA) via the 2-methylcitrate cycle II (propionate degradation route). PrpF catalyzes the cis-trans isomerization of 2-methyl-aconitate through a base-catalyzed proton abstraction coupled with a rotation about C2-C3 bond of 2-methyl-aconitate.
Similarity
Belongs to the PrpF family.
