The nucleotide sequence of the biotin (bio) biosynthetic operon of Escherichia coli has been determined. The 5.8-kilobase region contains the five biotin operon genes, bioA, B, F, C, and D. and an open reading frame of unknown function. The operon is negatively regulated and divergently transcribed from a control region between the bioA and bioB genes. The product of the bioA gene, 7,8-diaminopelargonic acid aminotransferase, was discovered to be related to ornithine aminotransferase. The product of the bioF gene, 7-keto-8-aminopelargonic acid synthetase, was found to be similar to 5-aminolevulinic acid synthetase.

D004926 Escherichia coli A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc. Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
