title: Chromosomal location of mutations affecting the regualtion of biotin synthesis in Escherichia coli.
abstract: The chromosomal locations of biotin regulatory mutations, birA, bioR, and dhbB, of Escherichia coli are determined by transduction using phage P1.  All mutant genes are mapped between bfe and supM.
