Table 2 Hybridization on DNA membranes of cDNA from transcripts expressed in cells grown with MTR or methionine as the sulfur source (normalized arbitrary units).

From: MtnK, methylthioribose kinase, is a starvation-induced protein in Bacillus subtilis

  1. Two different DNA membranes were used (A and B). The transcription hybridization level is given for genes at the mtn locus and, for comparison, genes expressed at a high level in the same experiment (translation: rplJ and tufA, replication and recombination: polA and polC, and DNA supercoiling: gyrA)
