Rv3097c of Mycobacterium tuberculosis encoding lipase (LipY) was overexpressed in Mycobacterium bovis BCG. Immunogenicity of BCG vaccine was impaired by LipY-induced hydrolysis of specific lipids leading to suppression of host immune responses.

The role of the PE domain in ESX-5 secretion was confirmed in a whole cell lipase assay, in which wild-type bacteria expressing full-length LipYtub, but not LipYtub lacking its PE domain, were shown to hydrolyze extracellular lipids. In conclusion, both PE and PPE domains contain a signal required for secretion of LipY by the ESX-5 system, and these domains are proteolytically removed upon translocation.

We have characterized the triacylglycerol (TAG) hydrolase LipY from Mycobacterium tuberculosis. Results suggest that the PE domain modulates enzyme activity.

We show that Rv3097c (LIPY) hydrolyzed long-chain TG with high specific activity. We demonstrate that hypoxic cultures of M. tuberculosis, which had accumulated TG, hydrolyzed the stored TG when subjected to nutrient starvation. Under such conditions, lipY was induced more than all lipases, suggesting a central role for it in the utilization of stored TG. We also show that in the lipY-deficient mutant, TG utilization was drastically decreased under nutrient deprived condition.
