Updated annotation (from data): acetylornithine aminotransferase (EC 2.6.1.11); succinylornithine aminotransferase (EC 2.6.1.81) Rationale: Important for fitness in many minimal media experiments, and mostly rescued by addition of arginine, which suggests a role as acetylornithine aminotransferase. Important for utilization of arginine as a nitrogen source, which suggests a role as succinylornithine aminotransferase in the AST pathway. 65% identical to O30508 (AruC) from P. aeruginosa, which is reported to have these two activities. Original annotation: bifunctional N-succinyldiaminopimelate-aminotransferase/acetylornithine transaminase protein Type 1: Protein-coding gene Located on scaffold CP001978, - strand, nucleotides 3,188,964 to 3,190,178 See nucleotide sequence around HP15_3042 or for all of scaffold CP001978
