Leu/Ile/Val-binding protein (IPR000709)

Short name: Leu_Ile_Val-bd

Overlapping homologous superfamilies

Family relationships



Leu/Ile/Val/Thr- and Leu-binding proteins, which share a high degree of sequence similarity, are components of the leucine-specific transport system. This is one of two periplasmic binding protein-dependent systems in the high-affinity transport of branched-chain amino acids in bacteria [PMID: 3891753, PMID: 2649682]. A much weaker sequence relationship has been reported between the periplasmic binding proteins and the aliphatic amidase expression-regulating protein, AmiC. On this basis, it has been suggested that AmiC may be capable of adopting a similar 3D fold [PMID: 8253087].
