Identification of Rv3230c as the NADPH oxidoreductase of a two-protein DesA3 acyl-CoA desaturase in Mycobacterium tuberculosis H37Rv.

DesA3 is a membrane-bound stearoyl-CoA Delta(9)-desaturase that produces oleic acid, a precursor of mycobacterial membrane phospholipids and triglycerides. The sequence of DesA3 is homologous with those of other membrane desaturases, including the presence of the eight-His motif proposed to bind the diiron center active site. This family of desaturases function as multicomponent complexes and thus require electron transfer proteins for efficient catalytic turnover. Here we present evidence that Rv3230c from Mycobacterium tuberculosis H37Rv is a biologically relevant electron transfer partner for DesA3 from the same pathogen. For these studies, Rv3230c was expressed as a partially soluble protein in Escherichia coli; recombinant DesA3 was expressed in Mycobacterium smegmatis as a catalytically active membrane protein. The addition of E. coli lysates containing Rv3230c to lysates of M. smegmatis expressing DesA3 gave strong conversion of [1-(14)C]-18:0-CoA to [1-(14)C]-cis-Delta(9)-18:1-CoA and of [1-(14)C]-16:0-CoA to [1-(14)C]-cis-Delta(9)-16:1-CoA. Both M. tuberculosis proteins were required for reconstitution of activity, as various combinations of control lysates lacking either Rv3230c or DesA3 gave minimal or no activity. Furthermore, the specificity of interaction between Rv3230c and DesA3 was implied by the inability of other related redox systems to substitute for Rv3230c. The reconstituted activity was dependent upon the presence of NADPH, could be saturated by increasing the amount of Rv3230c added, and was also sensitive to the salt concentration in the buffer. The results are consistent with the formation of a protein-protein complex, possibly with electrostatic character. This work defines a multiprotein, acyl-CoA desaturase complex from M. tuberculosis H37Rv to minimally consist of a soluble Rv3230c reductase and integral membrane DesA3 desaturase. Further implications of this finding relative to the properties of other multiprotein iron-enzyme complexes are discussed. << Less
