Identification
Name:Fumaric acid
Description:A precursor to L-malate in the Krebs tricarboxylic acid cycle. It is formed by the oxidation of succinate by succinate dehydrogenase. Fumarate is converted by fumarase to malate. A fumarate is a salt or ester of the organic compound fumaric acid, a dicarboxylic acid. (wikipedia)

Responsible for the aerobic transport of the dicarboxylates fumarate, L- and D-malate and to a lesser extent succinate, from the periplasm across the inner membrane
Gene Name:
dctA
Uniprot ID:
P0A830
Molecular weight:
45436
General function:
Involved in transporter activity
Specific function:
OmpF is a porin that forms passive diffusion pores which allow small molecular weight hydrophilic materials across the outer membrane. It is also a receptor for the bacteriophage T2
