The microarray data related to YmdB overexpression

The microarray data related to YmdB overexpression Linsitinib mouse were compared with the tiling array data for an RNase III mutant [36], in which 592 genes were affected by the absence of RNase III. Of 127 coding genes from the tiling array data, 47 are known RNase III targets and, of these, 37

were similarly regulated by YmdB and the RNase III mutant (Additional file 1: Table S3). This suggests that YmdB modulates these genes by down-regulating RNase III activity. However, 80 genes that were not previously regarded as RNase III targets also appeared to be modulated via an as yet uncharacterized YmdB function(s). When the 80 genes were classified according to the biological process in which they are involved, we Pevonedistat solubility dmso identified ten different cellular processes that were modulated by YmdB induction (Table 1). Therefore, the data indicate that YmdB, either as an RNase III regulator or by itself, participates in the regulation of multiple cellular processes within E. coli.
