CC -!- FUNCTION: GDSL lipase that catalyzes the hydrolysis of p-nitrophenyl
CC (pNP) esters. pNP-decanoate (C10) is the preferred substrate. It can
CC also use pNP-octanoate (C8), pNP-dodecanoate (C12) and pNP-
CC tetradecanoate (C14). Has lower activity with pNP-butyrate (C4), pNP-
CC palmitate (C16) and pNP-stearate (C18) (PubMed:31125644). Does not show
CC phospholipase A1 activity (PubMed:31125644). Might help bacteria to
CC utilize available lipids for its growth as well as provide resistance
CC to various intracellular stresses by cell wall modulation resulting in
CC enhanced intracellular survival (PubMed:31125644).
CC {ECO:0000269|PubMed:31125644}.

CC -!- ACTIVITY REGULATION: Activity is inhibited by the serine modifier
CC phenylmethylsulfonyl fluoride (PMSF). {ECO:0000269|PubMed:31125644}.
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=400 uM for pNP-decanoate {ECO:0000269|PubMed:31125644};
CC Note=kcat is 14440 min(-1) with pNP-decanoate as substrate.
CC {ECO:0000269|PubMed:31125644};
CC pH dependence:
CC Optimum pH is 9.0 (with pNP-decanoate as substrate).
CC {ECO:0000269|PubMed:31125644};
CC Temperature dependence:
CC Optimum temperature is 40 degrees Celsius (with pNP-decanoate as
CC substrate). {ECO:0000269|PubMed:31125644};
CC -!- SUBCELLULAR LOCATION: Secreted, cell wall
CC {ECO:0000269|PubMed:31125644}. Secreted, extracellular space
CC {ECO:0000269|PubMed:31125644}.
CC -!- INDUCTION: Expression is up-regulated under nutrient starvation (in
CC strain H37Ra). {ECO:0000269|PubMed:31125644}.
CC -!- MISCELLANEOUS: Expression in M.smegmatis alters colony morphology and
CC growth kinetics, provides resistance to SDS, lysozyme and anti-TB
CC drugs, increases the total lipid content and trehalose dimycolates, and
CC enhances infection ability and intracellular survival capability of
CC M.smegmatis. {ECO:0000269|PubMed:31125644}.
CC -!- SIMILARITY: Belongs to the 'GDSL' lipolytic enzyme family.
CC {ECO:0000305}.
