FIG 2.

IS1415 insertions in the genome of R. erythropolis strain MI2 and identification of genes adjacent to the insertion loci. Insertion of the IS1415 element into the genome of R. erythropolis strain MI2 fully impaired the growth of the cells on DTDB. The insertion loci in all the transposon-induced mutants are indicated. The lengths and directions of arrows representing the genes affected indicate the proportional lengths and directions of transcription of those genes. Putative identities of the gene products are suggested from the identities of amino acid sequences to those of proteins in the GenBank database. ORF, open reading frame. The genes shown encode the following proteins: noxR, transcriptional regulator of the TetR family; nox, NADH:flavin oxidoreductase; trx, thioredoxin reductase; the Hip A-C gene, homeodomain-interacting protein kinase; ftsK, bacterial cell division protein.
