Exploring Riboswitches in Archaeal Metagenomes

Metagenomics is defined as the direct analysis of genomes found in an environmental sample. It involves cloning and analyzing the genomes without culturing the organisms in the community. A number of new and novel molecules with significant functionalities and applications have been identified through this approach. This study focuses on identifying riboswitches in Archaeal metagenomes. Instances of TPP and Ado-Cbl variant riboswitches have been identified in different uncultured archaeal metagenomes. These riboswitches were searched and verified by using various bioinformatics approaches. The findings in Archaeal metagenomes hint at the possibility of finding more predefined and novel classes of riboswitches as new genomic samples are extracted from the environment.
