Disease
LTC4S_HUMAN Defects in LTC4S are the cause of leukotriene C4 synthase deficiency (LTC4 synthase deficiency) [MIM:246530. LTC4 synthase deficiency is a fatal neurometabolic developmental disorder. It is associated with muscular hypotonia, psychomotor retardation, failure to thrive, and microcephaly.
Function
LTC4S_HUMAN Catalyzes the conjugation of leukotriene A4 with reduced glutathione to form leukotriene C4.
Publication Abstract from PubMed
Dodecyl-beta-D-selenomaltoside (SeDDM) is a seleno-detergent with a beta-glycosidic seleno-ether in place of the ether moiety in dodecyl-beta-D-maltoside. Seleno-detergents are candidates for heavy-atom agents in experimental phasing of membrane proteins in protein crystallography. Crystals of a nuclear membrane-embedded enzyme, leukotriene C(4) synthase (LTC(4)S), in complex with SeDDM were prepared and a multiwavelength anomalous diffraction (MAD) experiment was performed. The SeDDM in the LTC(4)S crystal exhibited sufficient anomalous diffraction for determination of the structure using MAD phasing.
