Regulation of phospholipase D [PDF]
Structural studies of plant and bacterial members of the phospholipase D (PLD) superfamily are providing information about the role of the conserved HKD domains in the structure of the catalytic center and the catalytic mechanism of mammalian PLD isozymes (PLD1 and PLD2).

Phospholipase A2 Biochemistry [PDF]
The phospholipase A(2) (PLA(2)) superfamily consists of many different groups of enzymes that catalyze the hydrolysis of the sn-2 ester bond in a variety of different phospholipids. The products of this reaction, a free fatty acid, and lysophospholipid have many different important physiological roles.

A Piece of the Lepton Theory from a Probability [PDF]
A masses of a leptons deduced from a representation of a probability density vector by a spinors. A massive W and Z bosons and a massless A boson are obtained from a transformations for which a density vector is invariant.

The emerging roles of PAF acetylhydrolase
Platelet-activating factor (PAF), a phospholipid autacoid with potent effects throughout the innate immune system, is selectively degraded by two small families of PAF acetylhydrolases (PAF-AHs).

On a question of A. Balog [PDF]
We give a partial answer to a conjecture of A. Balog, concerning the size of AA+A, where A is a finite subset of real numbers. Also, we prove several new results on the cardinality of A:A+A, AA+AA and A:A + A:A.

Mammalian Phospholipase A2: Phospholipase A2 Receptor
The phospholipase A2 receptor (PLA2R) is a type I transmembrane glycoprotein related to the C-type animal lectin family such as the mannose receptor. PLA2R regulates a variety of biological responses elicited by secretory phospholipase A2s (sPLA2s). Group IB sPLA2 acts as an endogenous ligand to induce cell proliferation and lipid mediator production ...

Enumeration of symmetric centered rhombus tilings of a hexagon [PDF]
A rhombus tiling of a hexagon is said to be centered if it contains the central lozenge. We compute the number of vertically symmetric rhombus tilings of a hexagon with side lengths $a, b, a, a, b, a$ which are centered. When $a$ is odd and $b$ is even, this shows that the probability that a random vertically symmetric rhombus tiling of a $a, b, a, a ...

The substrate specificity of phospholipase A
Investigations on variously modified analogues of phospholipids elucidated the following substrate characteristics for phospholipase A (Crotalus adamanteus). 1. 1. Within the class of α-phosphoglycerides l-isomers are readily hydrolysed, while d-α-phospholipids appeared not to be attacked. 2. 2.

Phospholipase Cβ2 Binds to and Inhibits Phospholipase Cδ1 [PDF]
Phospholipase Cβ (PLCβ) isoforms, which are under the control of Gαq and Gβγ subunits, generate Ca2+ signals induced by a broad array of extracellular agonists, whereas PLCδ isoforms depend on a rise in cytosolic Ca2+ for their activation. Here we find that PLCβ2 binds strongly to PLCδ1 and inhibits its catalytic activity in vitro and in living cells ...
