| 설명 | 염기, 당, 인산으로 이루어진 뉴클레오티드가 긴 사슬 모양으로 중합된 고분자 물질. 유전이나 단백질 합성을 지배하는 중요한 물질로, 생물의 증식을 비롯한 생명 활동 유지에 중요한 작용을 한다. 구성 당인 오탄당이 리보오스인 리보핵산과 디옥시리보오스인 디옥시리보 핵산으로 나뉜다. 펜토스로서 리보스나 데옥시리보스 어느 한쪽만을 포함하며 전자를 리보핵산(RNA), 후자를 데옥시리보핵산(deoxyribonucleic acid, DNA)이라 부른다. 모두 4종류의 유기염기에 의해 특징지어지며 아데닌, 구아닌 및 시토신은 양자에 공통이다. 티민은 DNA에, 우라실은 RNA에 포함된다. DNA는 주로 핵에 존재하며 형질유전에 그리고 RNA는 세포질속에서 단백질 합성에 관여한다. 섭취된 핵산은 소화관에서 구성분자로까지 가수분해되어 흡수된다. |

| phosphatidate phosphatase | <enzyme> A phosphomonoesterase involved in the synthesis of triacylglycerols. It catalyses the hydrolysis of phosphatidates with the formation of diacylglycerols and orthophosphate. Chemical name: 3-sn-Phosphatidate phosphohydrolase Registry number: EC 3.1.3.4 (12 Dec 1998) |
| phosphatidylinositol-3,4,5-trisphosphate 5-phosphatase | <enzyme> Hydrolyzes the 5-position phosphate of ptdins(3,4,5)p3 forming phosphatidylinositol-3,4-bisphosphate; an isoenzyme forms a complex with the p85/p110 form of pi 3-kinase Registry number: EC 3.1.3.- Synonym: ptdins(3,4,5)p3 5-phosphatase, pi(3,4,5)p3 5-pase (26 Jun 1999) |
| phosphatidylinositol-3-phosphatase | <enzyme> Hydrolyzes phosphatidylinositol 3-phosphate in nih 3t3 cells; specific as it has little or no activity on the monoester phosphates of ptdins(4)p, ptdins(4,5)p2, or inositol 1,3-bisphosphate; does not require added metal ions for activity and is maximally active in the presence of edta; inhibited by ca(2+), mg(2+),zn(2+), and the phosphatase inhibitor vo(3-)4 Registry number: EC 3.1.3.64 Synonym: phosphatidylinositol 3-phosphatase (26 Jun 1999) |
| phosphatidylinositol 4-phosphate phosphatase | <enzyme> From human erythrocyte membranes Registry number: EC 3.1.3.- Synonym: ptdins-4p-phosphatase, phosphatidylinositol-4-phosphate monoesterase, ptdins4p monoesterase (26 Jun 1999) |
| phosphocholine phosphatase | <enzyme> Unlike alkaline phosphatase the hamster heart enzyme has a different pH optimum and heat sensitivity and is not inhibited by amino acids Registry number: EC 3.1.3.- (26 Jun 1999) |
| phosphofructokinase phosphatase | <enzyme> May be an aspect of EC 3.1.3.16 Registry number: EC 3.1.3.- Synonym: pfk-inactivating enzyme (26 Jun 1999) |

| phosphoprotein phosphatase | <enzyme> A group of enzymes removing the serine- or threonine-bound phosphate groups from a wide range of phosphoproteins, including a number of enzymes which have been phosphorylated under the action of a kinase. (enzyme nomenclature, 1992) Chemical name: Phosphoprotein phosphohydrolase Registry number: EC 3.1.3.16 (12 Dec 1998) |
