Comparative genomics boosts target prediction for bacterial small RNAs.
Small RNAs (sRNAs) constitute a large and heterogeneous class of bacterial gene expression regulators. Much like eukaryotic microRNAs, these sRNAs typically target multiple mRNAs through short seed pairing, thereby acting as global posttranscriptional regulators. In some bacteria, evidence for hundreds to possibly more than 1,000 different sRNAs has been obtained by transcriptome sequencing. Ho...
متن کاملComparative genomics of small RNAs in bacterial genomes.
In recent years, various families of small non-coding RNAs (sRNAs) have been discovered by experimental and computational approaches, both in bacterial and eukaryotic genomes. Although most of them await elucidation of their function, it has been reported that some play important roles in gene regulation. Here we carried out comparative genomics analysis of possible sRNAs that are computational...
متن کاملTarget prediction for small, noncoding RNAs in bacteria
Many small, noncoding RNAs in bacteria act as post-transcriptional regulators by basepairing with target mRNAs. While the number of characterized small RNAs (sRNAs) has steadily increased, only a limited number of the corresponding mRNA targets have been identified. Here we present a program, TargetRNA, that predicts the targets of these bacterial RNA regulators. The program was evaluated by as...
متن کاملAn assessment of bacterial small RNA target prediction programs
Most bacterial regulatory RNAs exert their function through base-pairing with target RNAs. Computational prediction of targets is a busy research field that offers biologists a variety of web sites and software. However, it is difficult for a non-expert to evaluate how reliable those programs are. Here, we provide a simple benchmark for bacterial sRNA target prediction based on trusted E. coli ...
متن کاملSmall RNAs in Bacterial Cell-Cell Communication
M any types of free-living bacteria communicate with one another by chemical signals, thereby coordinating metabolic activities and developmental processes. For instance, starved cells of the myxobacterium Myxococcus xanthus release the A signal, a mixture of six amino acids, to promote aggregation, the first step in the development of a fruiting body. Escherichia coli cells coordinate their mo...
