Mrub_3019 Casa Gene Is An Ortholog To E. Coli B2760, Kelsey Heiland, Dr. Lori Scott

Meiothermus ruber Genome Analysis Project

This research is part of the Meiothermus ruber genome annotation project which aims to predict gene function with various bioinformatics tools. We investigated the function of Mrub_3019, which encodes the CasA protein involved in the multi-subunit effector complex for the CRISPR-Cas immunity system and predicted it to be an ortholog of E. coli K12 MG1655 b2760 (casA). We predicted that Mrub_3019 encodes the protein CasA, which is involved in PAM recognition of CRISPR interference pathway. Foreign DNA will bind to CasA, which signals Cas3 for helicase-mediated DNA degradation. Our hypothesis is supported by low E-values for pairwise alignment in NCBI ...
