Thaum lub sijhawm txhais lus, elongation ntawm polypeptide tshwm sim los ntawm kev sib ntxiv ntawm cov amino acids sib txawv. Tsim ntawm thawj thiab tom qab peptide daim ntawv cog lus tshwm sim ntawm dawb-COOH pawg ntawm peptidyl tRNA ntawm P site thiab dawb NH2 pawg aminoacyl tRNA ntawm ib qhov chaw nrog kev pab ntawm peptidyl transferase enzyme.
Peptide bonds tsim thaum lub sij hawm elongation?
Thaum lub sijhawm elongation, lub ribosome txuas ntxiv txhais txhua codon nyob rau hauv lem. Txhua qhov sib txuas amino acid yog ntxiv rau cov saw loj hlob thiab txuas los ntawm daim ntawv cog lus hu ua peptide daim ntawv cog lus.
Peptide daim ntawv cog lus li cas ntawm cov amino acids hauv cov txheej txheem elongation?
Kev txhais elongation hauv eukaryotes.: Thaum lub sij hawm txhais lus elongation, cov aminoacyl-tRNA nkag mus rau ribosome A site, qhov twg nws khi yog tias tRNA anticodon ntxiv rau A site mRNA codon. … Qhov no tsim ib daim ntawv cog lus peptide nruab nrab ntawm C terminus ntawm cov saw polypeptide loj hlob thiab A site amino acid.
Peptide bonds tsim theem twg?
Ib daim ntawv cog lus peptide yog cov tshuaj lom neeg tsim los ntawm ob lub molecules thaum pawg carboxyl ntawm ib lub molecule reacts nrog cov amino pawg ntawm lwm cov molecule, tso ib tug molecule dej (H2O). Qhov no yog dehydration synthesis tshuaj(tseem hu ua cov tshuaj tiv thaiv condensation), thiab feem ntau tshwm sim ntawm cov amino acids.
Peptide daim ntawv cog lus ua li cas?
Daim ntawv cog lus uas tuav ua ke ob lub aminoacids yog ib tug peptide daim ntawv cog lus, los yog covalent tshuaj daim ntawv cog lus ntawm ob lub tebchaw (qhov no, ob amino acids). Nws tshwm sim thaum pawg carboxylic ntawm ib lub molecule reacts nrog cov amino pawg ntawm lwm cov molecule, txuas ob lub molecules thiab tso cov dej molecule.
