Next Generation Sequencing Facilitates Quantitative Analysis of Mycobacterium smegmatis C2 155 Transcriptomes treated with rifampicin and glutamine

We report the application of single-molecule-based sequencing technology for high-throughput profiling of histone modifications in mycobacterium smegmatis C2 155. By obtaining over four billion bases of sequence from chromatin immunoprecipitated DNA, we generated genome-wide chromatin-state maps of Mycobacterium smegmatis C2 155. We find that amino acids synthesis and degradation genes, genes that are expressed.The ratio of gene expression based on transcriptome substantiate an enhanced TCA cycle. The upregulation of Lys1 was found to prompt this degradation of lysine. The transformation from glutamine to glutamate as well as arginine was mediated by glsA (MSMEG_3818) , of which glutamate engaged into the TCA cycle via α-ketoglutarate. The phenylalanine was degraded into fumarate via mhpB. The succinate formation from asparate degradation was mediated by methylcitrate dehydratase (MSMEG_6645), carboxyvinyl-carboxyphosphonate phosphorylmutase (MSMEG_2506) and MSMEG_6855. and therefore reflect metabolism state of strains. Data from sample treated with rifampicin/glutamine reveals the upregulation of respiration. mRNA profiles of M.smegmatis exposed in rifampicin with or without glutamine were generated by deep sequencing, using Illumina Hiseq.
