Updated annotation (from data): lysine/tyrosine outer membrane transporter, accessory component Rationale: Specifically important in nitrogen source L-Lysine; nitrogen source L-tyrosine disodium salt. Echvi_4215 is an outer membrane lipoprotein that has very similar phenotypes as an adjacent TonB-dependent receptor (Echvi_4214). Jackhmmer searches found that Echvi_4215 is distantly related to DUF4374; both Echvi_4215 and DUF4374 have conserved proximity to TonB-dependent receptors. Echvi_4215 and relatd proteins are probably accessory proteins for uptake, analagous to the SusD family, but not homolgous. (SusD-like proteins are not found in proximity to Echvi_4214 or its homologs.) Original annotation: hypothetical protein Type 1: Protein-coding gene Located on scaffold Echvi_Contig97.1, + strand, nucleotides 5,048,551 to 5,049,885 See nucleotide sequence around Echvi_4215 or for all of scaffold Echvi_Contig97.1
