Cloning and expression of proteins from Mycobacterium smegmatis
... To identify the M. smegmatis homologues to the M. tuberculosis genes Rv3782, Rv3790 and Rv3791, a comparative analysis using the GenMycDB [3] server was performed. The comparative analysis resulted in several hit candidates. The E-value was used to find the candidate with highest sequence identity. ...
