Proline ua dab tsi rau lub cev

Proline hmoov yog dab tsi?
Proline protein hmoovyog ib qho organic acid, uas belongs rau qeb ntawm cov protein amino acids. Nws yog ib qho tsis tseem ceeb ntawm tib neeg lub cev. Nws tuaj yeem tsim los ntawm cov amino acid uas tsis tseem ceeb L-glutamic acid. Proline hmoov yog ib qho protein thib ob amino acid raws li qhov thib ob amine, yog ib qho kev hloov kho osmotic uas pab khaws cov nitrogen thiab carbon rau hauv cov nroj tsuag, thiab yog dawb crystalline hmoov los yog crystalline hmoov nyob rau hauv tsos.

 

Yuav ua li cas proline tsim?
Proline yog biosynthesized los ntawm cov amino acid L-glutamate. Glutamate-5-semialdehyde yog thawj tsim los ntawm glutamate 5-kinase (ATP-dependent) thiab glutamate-5-semialdehyde dehydrogenase (NADH lossis NADPH-yuav tsum tau). Tom qab ntawd nws tuaj yeem ua rau cyclize ib txwm los ua 1-pyrroline-5-carboxylic acid, uas txo qis rau proline los ntawm pyrroline-5-carboxylic acid reductase (siv NADH lossis NADPH), lossis hloov mus rau proline los ntawm ornithine aminotransferase Ornithine, uas yog ces cyclized rau proline los ntawm ornithine nplhaib deaminase.

 

Ntuj qhov chaw ntawm Proline:
Cov khoom noj zoo tshaj plaws ntawm proline muaj xws li nqaij, khoom noj siv mis, thiab qe.

 

Cov qauv protein ntawm proline hmoov yog dab tsi?
Cov qauv nplhaib tshwj xeeb ntawm sab saw ntawm proline ua rau proline muaj kev sib haum xeeb zoo heev piv nrog lwm cov amino acids. Nws kuj cuam tshuam rau tus nqi ntawm peptide daim ntawv cog lus ntawm proline thiab lwm yam amino acids. Thaum proline raug khi rau ib qho amide hauv peptide daim ntawv cog lus, nws cov nitrogen tsis khi rau ib qho hydrogen, uas txhais tau hais tias nws tsis tuaj yeem ua raws li tus neeg pub nyiaj hydrogen, tab sis tuaj yeem ua raws li tus neeg txais nyiaj hydrogen.
Peptide daim ntawv cog lus tsim nrog Pro-tRNAPro tuaj yeem qeeb qeeb dua li lwm yam tRNA, tus yam ntxwv ntawm N-alkyl amino acids. Peptide daim ntawv cog lus tsim los ntawm cov khoom tRNA thiab cov saw proline-terminated kuj qeeb; proline-proline bonds yog qhov qeeb tshaj plaws los tsim.
Qhov tshwj xeeb conformational rigidity ntawm proline cuam tshuam rau theem nrab cov qauv ntawm cov proteins nyob ze proline residues thiab yuav piav qhia txog qhov ntau dua ntawm proline hauv thermophilic biological proteins. Cov qauv protein thib ob tuaj yeem piav qhia los ntawm dihedral ces kaum φ, ψ thiab ω ntawm cov pob txha protein. Lub nplhaib qauv ntawm proline sab saw xauv lub kaum sab xis φ ntawm kwv yees li -65 degree .
Proline ua raws li tus qauv cuam tshuam nyob rau hauv nruab nrab ntawm cov qauv theem nrab cov qauv xws li -helices thiab -sheets; Txawm li cas los xij, proline feem ntau tshwm sim raws li thawj qhov seem ntawm -helices thiab kuj nyob rau hauv ntug strands ntawm -sheets. Proline kuj feem ntau pom nyob rau hauv lem (lwm tus qauv theem nrab) thiab pab txhawb rau kev tsim ntawm beta lem. Qhov no yuav piav qhia qhov txawv qhov tseeb tias proline feem ntau raug rau cov kuab tshuaj, txawm tias muaj tag nrho cov aliphatic sab saw.
Kev sib txuas ntau yam prolines thiab / lossis hydroxyprolines tuaj yeem tsim polyproline helices, cov qauv loj thib ob hauv collagen. Hydroxylation ntawm proline los ntawm prolyl hydroxylase (lossis ntxiv lwm cov khoom siv hluav taws xob rho tawm xws li fluorine) ua rau kom muaj kev ruaj ntseg ntawm collagen. Yog li, hydroxylation ntawm proline yog txheej txheem biochemical tseem ceeb rau kev tswj cov ntaub so ntswg hauv cov kab mob siab dua. Cov kab mob hnyav xws li scurvy tuaj yeem tshwm sim los ntawm qhov tsis xws luag hauv hydroxylation, xws li kev hloov pauv hauv prolyl hydroxylase lossis qhov tsis txaus ntawm qhov tseem ceeb ascorbic acid (vitamin C) cofactor.

 

Lub luag haujlwm ntawm proline hauv cov nroj tsuag loj hlob yog dab tsi?
1. Kev faib tawm ntawm Proline hauv cov nroj tsuag:
Cov dawb proline nyob rau hauv cov nroj tsuag feem ntau yog faib nyob rau hauv photosensitive lub cev nqaij daim tawv thiab lub cev xeeb tub, thiab tsawg faib nyob rau hauv lwm yam kabmob hauv Suav teb. Dawb proline hmoov feem ntau yog concentrated nyob rau hauv lub cev uas muaj zog metabolism thiab cov plab hnyuv siab raum, uas muaj peev xwm muab qhov tseem ceeb rau kev tiv thaiv cov nroj tsuag thaum cov nroj tsuag raug hem Organs uas pab tswj cov nroj tsuag loj hlob.
2. Lub ntsiab lus tseem ceeb ntawm proline (Proline) tsub zuj zuj hauv qab ntsev:
Cov nroj tsuag feem ntau tau txais ob txoj hauv kev los khaws cov proline hauv qab ntsev kev nyuaj siab: ib qho yog tias thaum cov nroj tsuag ntsib kev nyuaj siab osmotic, cov ntsev muaj kev ntxhov siab ntau dhau los ntawm ntau theem ntawm txoj kev taw qhia, ua rau kev nthuav qhia cov noob muaj feem xyuam rau cov tshuaj osmoregulatory, ua rau muaj kev ntxhov siab vim. cov khoom lag luam, uas pab tswj qhov sib npaug ntawm cov hlwb hauv lub cev; Lwm txoj hauv kev yog thauj cov proline khaws cia hauv lub vacuole mus rau cytoplasm kom ua proline nyob rau hauv lub cell, pab cov nroj tsuag tiv thaiv ib puag ncig ntawm siab concentration ntawm ntsev.
3. Proline yog ib qho zoo tagnrho osmotic hloov tshuaj: Proline muaj ib tug me me molecular hnyav thiab yog ib tug protein-zoo li amino acid uas yog yooj yim soluble nyob rau hauv dej. Nws tsis nqa ib qho nqi ntawm pH li qub thiab yuav tsis ua rau muaj kev hloov pauv enzyme. Cov tshuaj tiv thaiv, cov no yuav ua rau cov hmoov proline ua lub luag haujlwm tseem ceeb hauv ib puag ncig tsis zoo. Proline yog ib qho zoo heev soluble amino acid, nplua nuj nyob rau hauv cov nroj tsuag, uas yuav pab tau cov nroj tsuag nce dej nqus, stabilizes dej tuav lub peev xwm ntawm lub hlwb, thiab stabilize proteins los muab cov as-ham rau cov nroj tsuag.
4. Proline ntshiab hmoov kuj tuaj yeem txhim kho cov dej ib puag ncig ntawm cov cell membrane, txhim khu kev ruaj ntseg ntawm cov qauv membrane, txhawb cov tshuaj synthesis thiab ua pa ntawm cov nroj tsuag, thiab ua kom cov nroj tsuag noj qab nyob zoo.
