Abstract
The present invention relates to the isolation of a new gene, des, which encodes a M. tuberculosis protein named DES. The des gene appears to be conserved among different Mycobacteria species. The amino acid sequence of the DES protein contains two sets of motifs that are characteristic of the active sites of enzymes from the class II diiron-oxo protein family. Among this family of proteins, DES shares significant homology with soluble stearoyl-ACP desaturases. DES is a highly antigenic protein, which is recognized by human sera from patients infected with M. tuberculosis and M. leprae but not by sera from tuberculous cattle. Thus, the DES protein provides a useful tool for the serodiagnostic analysis of tuberculosis.
