2-Oxocarboxylic acids are the most elementary set of metabolites that includes pyruvate (2-oxopropanoate), 2-oxobutanoate, oxaloacetate (2-oxobutanedioate) and 2-oxoglutarate. This diagram illustrates the architecture of chain extension and modification reaction modules for 2-oxocarboxylic acids. The chain extension module
RM001 is a tricarboxylic pathway where acetyl-CoA derived carbon is used to extend the chain length by one. The chain modification modules
RM002 (including
RM032) and
RM033, together with a reductive amination step (
RC00006 or
RC00036), generate basic and branched-chain amino acids, respectively. The modification module
RM030 is used in the biosynthesis of glucosinolates, a class of plant secondary metabolites, for conversion to oxime followed by addition of thio-glucose moiety. This diagram also includes corresponding KEGG modules for each of the reaction modules.
