Crystal structure of mammalian acid sphingomyelinase
Acid sphingomyelinase (ASMase, ASM, SMPD1) converts sphingomyelin into ceramide, modulating membrane properties and signal transduction. Inactivating mutations in ASMase cause Niemann-Pick disease, and its inhibition is also beneficial in models of depression and cancer. To gain a better understanding of this critical therapeutic target, we determined crystal structures of mammalian ASMase in v...
متن کاملFunctional Assessment of an Overexpressed Arabidopsis Purple Acid Phosphatase Gene (Atpap26) in Tobacco Plants
Background: Overexpression of known genes encoding key phosphate (Pi)-metabolizing enzymes, such as acid phosphatases (APases), is presumed to help plants with Pi availability and absorption as they are mostly exposed to suboptimal environmental conditions for this vital element.Objectives: In this study, the overexpression effect of AtPAP26, one of the m...
متن کاملCrystallization and preliminary X-ray diffraction studies of mammalian purple acid phosphatase.
The oxidized form of purple acid phosphatase from pig allantoic fluid has been crystallized in the presence of phosphate using the hanging-drop technique. The crystals belong to the space group P2(1)2(1)2(1) and have unit-cell parameters a = 66.8, b = 70.3, c = 78.7 A. Diffraction data collected from a cryocooled crystal using a conventional X-ray source extend to 1.55 A resolution. A knowledge...
متن کاملTransfer of iron from uteroferrin (purple acid phosphatase) to transferrin related to acid phosphatase activity.
There is continuing controversy as to whether iron can be exchanged from the purple phosphatase, uteroferrin (Uf), to fetal transferrin (Tf) and whether this process might be of physiological relevance during pregnancy in the pig. Here, iron transfer from Uf to apoTf at pH 7.1 was followed by measuring the loss of acid phosphatase activity from native Uf as a function of incubation conditions a...
متن کاملInhibition of purple acid phosphatase with alpha-alkoxynaphthylmethylphosphonic acids.
Purple acid phosphatases (PAPs) are binuclear hydrolases that catalyse the hydrolysis of a range of phosphorylated substrates. Human PAP is a major histochemical marker for the diagnosis of osteoporosis. In patients suffering from this disorder, PAP activity contributes to increased bone resorption and, therefore, human PAP is a key target for the development of anti-osteoporotic drugs. This ma...
