Phosphatidylinositol Diacylglycerol-Lyase
|
D043265 |
[A phosphorus-oxygen lyase found primarily in BACTERIA. The enzyme catalyzes the cleavage of a phosphoester linkage in 1-phosphatidyl-1D-myo-inositol to form 1D-myo-inositol 1,2-cyclic phosphate and diacylglycerol. The enzyme was formerly classified as a phosphoric diester hydrolase (EC 3.1.4.10) and is often referred to as a TYPE C PHOSPHOLIPASES. However it is now known that a cyclic phosphate is the final product of this enzyme and that water does not enter into the reaction.

|
Phosphatidylinositol-3,4,5-Trisphosphate 5-Phosphatases
|
D000072183 |
[Phosphoinositide phosphatases that catalyze the dephosphorylation (hydrolysis) of phosphatidylinositol-3,4,5-trisphosphate (PtdIns(3,4,5)P(3)) to produce PtdIns(3,4)P(2), which negatively regulates the PI3K ( 3-PHOSPHOINOSITIDE-DEPENDENT PROTEIN KINASES) pathways. They contain an SH2 DOMAIN and STERILE ALPHA MOTIF and have important functions in regulating the immune response and other cellular processes in vertebrates.

Phosphatidylinositol-4-Phosphate 3-Kinase
|
D058538 |
[A phosphatidylinositol 3-kinase that catalyzes the conversion of 1-phosphatidylinositol 4-phosphate into phosphatidylinositol 3,4-bisphosphate.

Phosphatidylinositols
|
D010716 |
[Derivatives of phosphatidic acids in which the phosphoric acid is bound in ester linkage to the hexahydroxy alcohol, myo-inositol. Complete hydrolysis yields 1 mole of glycerol, phosphoric acid, myo-inositol, and 2 moles of fatty acids.

Phosphenes
|
D010719 |
[A subjective visual sensation with the eyes closed and in the absence of light. Phosphenes can be spontaneous, or induced by chemical, electrical, or mechanical (pressure) stimuli which cause the visual field to light up without optical inputs.

Phosphoadenosine Phosphosulfate
|
D010724 |
[3'-Phosphoadenosine-5'-phosphosulfate. Key intermediate in the formation by living cells of sulfate esters of phenols, alcohols, steroids, sulfated polysaccharides, and simple esters, such as choline sulfate. It is formed from sulfate ion and ATP in a two-step process. This compound also is an important step in the process of sulfur fixation in plants and microorganisms.

Phosphodiesterase I
|
D043264 |
[A phosphoric diester hydrolase that removes 5'-nucleotides from the 3'-hydroxy termini of 3'-hydroxy-terminated OLIGONUCLEOTIDES. It has low activity towards POLYNUCLEOTIDES and the presence of 3'-phosphate terminus on the substrate may inhibit hydrolysis.
