Updated annotation (from data): Histidinol-phosphatase (EC:3.1.3.15) Rationale: Annotated as HAD-superfamily IB hydrolase or sometimes as phosphoserine phosphatase (serB). However Psest_0489 seems to be serB and has auxotrophic phenotypes, so this is more likely the missing phosphatase for histidine synthesis. Fitness data for close homologs in other pseudomonads is consistent with this interpretation. (auxotroph) Original annotation: HAD-superfamily subfamily IB hydrolase, TIGR01490 Type 1: Protein-coding gene Located on scaffold Psest_Contig47.1, + strand, nucleotides 4,036,172 to 4,036,825 See nucleotide sequence around Psest_3864 or for all of scaffold Psest_Contig47.1
