Feem ntau, serine thiab threonine phosphosites yog hloov mus rau alanine (los yog valine rau threonine), thiab tyrosine phosphorylation sites yog hloov mus rau phenylalanine. Vim tias qhov loj spectrometry tuaj yeem nco cov chaw, nws yog ib qho tseem ceeb kom paub tseeb tias feem ntau lossis tag nrho cov chaw tseem ceeb tau txheeb xyuas thiab hloov pauv.

Cov amino acids twg tuaj yeem ua phosphorylated?

Phosphorylation feem ntau pom muaj nyob ntawm qhov tshwj xeeb serine thiab threonine amino acid residues hauv cov protein, tab sis nws kuj tshwm sim ntawm tyrosine thiab lwm cov amino acid residues (histidine, aspartic acid, glutamic acid.) thiab.

YPuas alanine tau phosphorylated?

Serine feem ntau hloov mus rau glutamic acid (qee zaum aspartic acid) kom ua raws li phosphorylation ntawm serine residue. Conversely, mutating serine rau alanine tiv thaiv muaj peev xwm phosphorylation. … Phosphorylation tshwm sim tom qab cov protein tau folded rau hauv nws qhov tseeb conformation.

YCov enzymes twg tuaj yeem ua phosphorylated?

Protein phosphorylation yog ib qho rov qab PTM uas yog kho los ntawm kinases thiab phosphatases, uas phosphorylate thiab dephosphorylate substrates, feem. Ob tsev neeg ntawm cov enzymes no pab txhawb qhov zoo ntawm phosphorylated proteins hauv ib lub cell.

YPeptide puas tuaj yeem ua phosphorylated?

Peptide phosphorylation yog peptide uas muaj phosphate (PO₄3-^{) pab pawg rau peptide muaj serine, threonine lossis tyrosine. …Protein phosphorylation tuaj yeem tshwm sim ntawm ntau cov amino acids. Phosphorylation ntawm serine yog feem ntau, ua raws li threonine.}
