The entomopathogenic bacterial endosymbionts Xenorhabdus and Photorhabdus: convergent lifestyles from divergent genomes

This is the genome sequencing paper for Xenorhabdus nematophila strain ATCC 19061, which identified the fliY gene (locus tag XNC1_0570) encoding the cysteine transport protein.

Deep research report on D3VIU4 fliY from Xenorhabdus nematophila

FliY serves as the periplasmic substrate-binding component of the FliY-YecSC (TcyJLN) ABC transporter complex for high-affinity L-cystine import. Studies in E. coli demonstrate that the FliY-YecSC system achieves half-maximal transport at approximately 30 nM cystine, about 100-fold higher affinity than the alternative YdjN transporter. The protein belongs to bacterial solute-binding protein family 3 and operates in the periplasmic space of Gram-negative bacteria.
