Updated annotation (from data): Putative D-serine transporter Rationale: Specific phenotype: utilization of D-Serine. This is a conserved phenotype, although AO356_05055 (DsdX) is also involved in D-serine uptake. 31% identical to PA14_1916, which is thought to be a citrate transporter based on genetic evidence (PMC9765132). Belongs to the rarD family (often annotated as chloramphenicol resistance, but the molecular function of E. coli rarD is not known) Original annotation: chloramphenical resistance permease RarD Type 1: Protein-coding gene Located on scaffold CP012831, - strand, nucleotides 3,204,028 to 3,204,915 See nucleotide sequence around AO356_14110 or for all of scaffold CP012831
