[https://www.uniprot.org/uniprot/LIP1_MALGO LIP1_MALGO] Secreted lipase involved in Dandruff and seborrheic dermatitis (D/SD) probably via lipase-mediated breakdown of sebaceous lipids and release of irritating free fatty acids (PubMed:17460728, PubMed:18000048). Shows activity against monoglyceride and diglyceride substrates, but not triglyceride substrates and does not exhibit regio-selective production of diacylglycerols (PubMed:17460728, PubMed:22750000, PubMed:25837472, PubMed:25955297, PubMed:26239010, PubMed:26365206, PubMed:27130210). Able to hydrolyze diacylglycerols such as distearin, dilinolein, dipalmitoylglycerol and dipalmitolein (PubMed:27130210). Cleaves oleic acid from 1,2 isomers of diolein on both the 1 and the 2 position of the glycerol backbone, resulting mainly in free fatty acids but no monoolein is detected (PubMed:27130210). Shows activity on monoolein and liberates mostly free fatty acids, but can also perform the reverse reaction and produce diolein (PubMed:27130210).<ref>PMID:17460728</ref> <ref>PMID:18000048</ref> <ref>PMID:22750000</ref> <ref>PMID:25837472</ref> <ref>PMID:25955297</ref> <ref>PMID:26239010</ref> <ref>PMID:26365206</ref> <ref>PMID:27130210</ref>

== Publication Abstract from PubMed ==

Most lipases contain a lid domain to shield the hydrophobic binding site from the water environment. The lid, mostly in helical form, can undergo a conformational change to expose the active cleft during the interfacial activation. Here we report the crystal structures of Malassezia globosa LIP1 (SMG1) at 1.45 and 2.60A resolution in two crystal forms. The structures present SMG1 in its closed form, with a novel lid in loop conformation. SMG1 is one of the few members in the fungal lipase family that has been found to be strictly specific for mono- and diacylglycerol. To date, the mechanism for this substrate specificity remains largely unknown. To investigate the substrate binding properties, we built a model of SMG1 in open conformation. Based on this model, we found that the two bulky hydrophobic residues adjacent to the catalytic site and the N-terminal hinge region of the lid both may act as steric hindrances for triacylglycerols binding. These unique structural features of SMG1 will provide a better understanding on the substrate specificity of mono- and diacylglycerol lipases and a platform for further functional study of this enzyme.
