Diaminopimelic acid (DAP) is an amino acid, representing an epsilon-carboxy derivative of lysine. meso -α,ε-Diaminopimelic acid is the last intermediate in the biosynthesis of lysine and undergoes decarboxylation by diaminopimelate decarboxylase to give the final product.
N-Acetylmuramic acid (NAM or MurNAc) is an organic compound with the chemical formula C 11 H 19 NO 8. It is a monomer of peptidoglycan in most bacterial cell walls, which is built from alternating units of N-acetylglucosamine (GlcNAc) and N-acetylmuramic acid, cross-linked by oligopeptides at the lactic acid residue of MurNAc.
Since 2020, due to COVID-19 pandemic in Vietnam and new entrance exams organised by universities and junior colleges, such as the Aptitude Tests (VNU, VNU-HCM, HNUE, HCMUE, Vietnamese police academies, etc.) and HUST Thinking Skills Assessment , the THPTQG has been discontinued, replaced by the High School Graduation Examination which is ...
2,6-DAP was used to treat leukemia since as early as 1951. [13] It is known to arrest progression of cell cycle in mouse leukemia cells by 1989. [ 14 ] Cancer cells are known to become resistant to DAP by losing their adenine phosphoribosyltransferase (APRT) function, [ 15 ] a process shared with E. coli .
Diammonium phosphate (DAP; IUPAC name diammonium hydrogen phosphate; chemical formula (NH 4) 2 (HPO 4)) is one of a series of water-soluble ammonium phosphate salts that can be produced when ammonia reacts with phosphoric acid. Solid diammonium phosphate shows a dissociation pressure of ammonia as given by the following expression and equation: [2]
DAP (gene), human gene that encodes death-associated proteins, which mediate programmed cell death Diamidophosphate, phosphorylating compound; Diaminopimelic acid, amino acid derivative of lysine
Comparable to phosphorylation, addition or removal of N-acetylglucosamine is a means of activating or deactivating enzymes or transcription factors. [4] In fact, O-GlcNAcylation and phosphorylation often compete for the same serine/threonine sites. [4] O-GlcNAcylation most often occurs on chromatin proteins, and is often seen as a response to ...
The SAT Subject Test in Biology was the name of a one-hour multiple choice test given on biology by the College Board. A student chose whether to take the test depending upon college entrance requirements for the schools in which the student is planning to apply. Until 1994, the SAT Subject Tests were known as Achievement Tests; and from 1995 ...
