Protein attributes

Sequence length	499 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Catalytic activity	(S)-malate = fumarate + H2O.
Pathway	Carbohydrate metabolism; tricarboxylic acid cycle; (S)-malate from fumarate: step 1/1.
Subcellular location	Plastid › chloroplast Potential.
Miscellaneous	There are 2 substrate binding sites: the catalytic A site, and the non-catalytic B site that may play a role in the transfer of substrate or product between the active site and the solvent. Alternatively, the B site may bind allosteric effectors By similarity.
Sequence similarities	Belongs to the class-II fumarase/aspartase family. Fumarase subfamily.
