Protein

Lysophospholipase

Gene

PLB

Organism
Kluyveromyces lactis (strain ATCC 8585 / CBS 2359 / DSM 70799 / NBRC 1267 / NRRL Y-1140 / WM37) (Yeast) (Candida sphaerica)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Catalyzes the release of fatty acids from lysophospholipids. At acidic pH the enzyme hydrolyzes all phospholipid substrates without metal ion. On the other hand, at alkaline pH the enzyme shows substrate specificity for phosphatidylcholine and lysophosphatidylcholine and requires Ca2+, Fe3+, or Al3+ for the activity.

Catalytic activityi

2-lysophosphatidylcholine + H2O = glycerophosphocholine + a carboxylate.

pH dependencei

Optimum pH is 2.0 and 7.5.
