Updated annotation (from data): ABC transporter for Carnitine, periplasmic substrate-binding component 1 Rationale: Specific phenotype on Carnitine Hydrochloride. This protein is similar to CaiX of P. syringae or P. aeruginosa (Psyr_2916 and PA5388) which has been shown to be a L-carnitine SBP (see PMID:19919675). Another gene in the cluster, AO356_13855, is also a SBP and is specifically important for L-carnitine utilization. AO356_13855 is similar to CbcX of P. aeruginosa or P. syringae (PA5378 or Psyr_4709) which is specific for choline or glycine betaine (ibid). Nevertheless, insertions in _13855 have a specific defect for carnitine utilization. It is possible that these insertions are polar on the beta-cleavage enzyme (_13850) which is required for carnitine catabolism. However insertions in _13855 in either orientation have a strong phenotype.
