Alpha-keto acid-binding periplasmic protein TakP

UniProtKB accession:  Q3J1R2

Grouped By:  Matching UniProtKB accession

UniProtKB description:  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.
