[https://www.uniprot.org/uniprot/TAKP_CERS4 TAKP_CERS4] Part of the tripartite ATP-independent periplasmic (TRAP) transport system TakPQM involved in the uptake of alpha-keto acids. This protein specifically binds alpha-keto acids including pyruvate, oxobutyrate, oxovalerate and 4-methyl-2-oxovalerate. Ligand-binding affinity increases with the increasing chain length of the aliphatic backbone of the ligand. Is not able to bind alpha-ketoglutarate.[UniProtKB:P44542]<ref>PMID:17362499</ref>
