Updated annotation (from data): 1-(5-phosphoribosyl)-5-((5-phosphoribosylamino)methylideneamino)imidazole-4-carboxamide isomerase (EC 5.3.1.16) Rationale: Important for fitness in most defined media. Semi-automated annotation based on the auxotrophic phenotype and a hit to HMM TIGR00007. Original annotation: 1-(5-phosphoribosyl)-5-[(5- phosphoribosylamino)methylideneamino] imidazole-4-carboxamide isomerase Type 1: Protein-coding gene Located on scaffold NC_003047, - strand, nucleotides 58,682 to 59,425 See nucleotide sequence around SMc02570 or for all of scaffold NC_003047
