Qhov sib txawv tseem ceeb ntawm endopeptidase thiab exopeptidase yog qhov endopeptidase tawg peptide bonds hauv cov protein molecules thaum exopeptidase cleaves peptide bonds ntawm cov terminals ntawm cov protein molecules.
Proteins yog ib qho tseem ceeb macromolecules, uas yog qhov tseem ceeb rau feem ntau ntawm cov tshuaj biochemical tshwm sim nyob rau hauv tag nrho cov kab mob. Cov amino acids sib txawv koom ua ke thiab tsim cov proteins no. Tsis tas li ntawd, enzymes catalyize hydrolysis ntawm cov proteins rov qab rau hauv cov amino acids. Lawv yog cov enzymes tshwj xeeb hu ua proteases lossis peptidases. Yog li ntawd, lawv muaj peev xwm ua kom tawg peptide chains ntawm cov proteins rau hauv cov amino acids. Ntxiv mus, peptidases tuaj yeem yog endopeptidases lossis exopeptidases.
YDab tsi yog Endopeptidase?
Endopeptidase yog ib hom protein-cleaving enzyme uas tawg peptide bonds hauv cov protein molecule. Raws li qhov tshwm sim ntawm cov tshuaj tiv thaiv endopeptidase, cov proteins faib ua cov saw peptide.
Daim duab 01: Endopeptidase – Chymotrypsin Action
Ntxiv mus, peptide chains yog cov kab ke ntawm cov amino acids. Yog li, ib qho amino acids tsis tshwm sim vim qhov kev ua ntawm endopeptidase. Hauv lwm lo lus, endopeptidases tsis tuaj yeem cais cov monomers ntawm cov proteins. Pepsin, Chymotrypsin, Thermolysin thiab Trypsin yog cov piv txwv rau endopeptidases.
Exopeptidase yog dab tsi?
Exopeptidases yog cov enzymes uas ua rau kev tawg ntawm peptide bonds ntawm cov terminals thiab tshem tawm ib qho amino acids los ntawm cov protein molecules.
Daim duab 02: Exopeptidase – Carboxypeptidase
Tsis tas li ntawd, carboxypeptidase thiab aminopeptidase yog ob hom exopeptidases. Dipeptidase yog lwm lub npe siv los xa tawm exopeptidase.
Dab tsi zoo sib xws ntawm Endopeptidase thiab Exopeptidase?
- ob leeg yog enzymes.
- YLawv yog cov protein.
- Endopeptidase thiab Exopeptidase catalyze hydrolysis ntawm cov proteins. Li no, lawv yog proteases.
- Lawv yog zais los ntawm lub plab, pancreas thiab plab hnyuv hlwb.
- Ob hom tseem ceeb hauv kev zom cov protein hauv peb lub cev.
Qhov txawv ntawm Endopeptidase thiab Exopeptidase yog dab tsi?
YPeptidases rhuav peptide bonds hauv cov proteins. Endopeptidase thiab exopeptidase yog ob hom ntawm ntau hom peptidases. Endopeptidases rhuav peptide bonds nyob rau hauv lub molecule thaum exopeptidases rhuav peptide bonds ntawm lub terminals. Yog li ntawd, peptide chains yuav tshwm sim vim qhov kev ua ntawm endopeptidases thaum monomers yuav tshwm sim vim qhov kev txiav txim ntawm exopeptidases. Enterokinase thiab enteropeptidase yog cov ntsiab lus ntawm endopeptidases thaum dipeptidase yog ib lub ntsiab lus rau exopeptidase. Cov nram qab no infographic nthuav qhia qhov sib txawv ntawm endopeptidase thiab exopeptidase raws li kev sib piv ntawm ib sab.
Summary – Endopeptidase vs Exopeptidase
Endopeptidase thiab exopeptidase yog ob hom peptidase enzymes. Lawv tshem cov peptide bonds hauv cov protein molecules. Cov enzymes no pab zom cov proteins hauv koj cov zaub mov. Lub plab, pancreas thiab lub plab zom mov tso tawm cov peptidases txhawm rau txhawm rau ua kom cov protein degradation thiab kev nqus zoo. Endopeptidase cleaves peptide bonds nyob rau hauv cov protein molecules thiab ua rau peptide chains, tsis yog cov monomers. Exopeptidase cleaves peptide bonds ntawm cov terminals thiab ua rau ib qho amino acids. Qhov no yog qhov txawv ntawm endopeptidase thiab exopeptidase.
