This experiment proved the absence of the fmt gene and showed that polypeptide deformylase, which has no substrates in the mutant is downregulated in OICR-9429 price Δfmt (Table  1). In addition, genes from several metabolic pathways were downregulated in Δfmt indicating that the absence of formylated proteins has pleiotrophic effects on transcription, which results probably either from dysfunctional regulatory proteins or from regulatory feedback events in metabolic pathways depending on formylated enzymes (see below).
