title: Insertion mutagenesis of the metJBLF gene cluster of Escherichia coli K-12: evidence for an metBL operon.
abstract: The effects of Mu or transposon 5 insertions on the expression of genes of the metJBLF cluster show that metB and metL form an operon, transcribed from metB to metL, and that metF and metJ are independently transcribed.
