Crystal Structure of (3R)-hydroxyacyl-ACP dehydratase HadAB hetero-dimer from Mycobacterium smegmatisCrystal Structure of (3R)-hydroxyacyl-ACP dehydratase HadAB hetero-dimer from Mycobacterium smegmatis
Structural highlights
FunctionPublication Abstract from PubMedFatty acid biosynthesis type II in mycobacteria delivers the fatty acids required for mycolic acid synthesis. The pathway employs a unique maoC like beta-hydroxyacyl-ACP dehydratase HadAB or HadBC heterodimer in the third step of the elongation cycle. Here we report the crystal structure of the HadAB complex determined using a Pb-SIRAS method. Crystal structure aided with enzymatic study establishes the roles of HadA as a scaffolding component and HadB as a catalytic component together indispensable for the activity. The detailed structural analysis of HadAB in combination with MD simulation endorses the spatial orientation of the central hot-dog helix and the dynamic nature of its associated loop in regulation of substrate specificities in dehydratase/hydratase family enzymes.
