Lwm Cov Ntawv Thov

 

• Kev Siv Tshuaj thiab Tshuaj Siv: L-leucine kuj tseem pom cov ntawv thov hauv cov txheej txheem kev lag luam thiab cov tshuaj lom neeg ua cov khoom siv raw lossis nruab nrab hauv kev tsim cov khoom tshwj xeeb. Txawm li cas los xij, cov ntsiab lus tshwj xeeb ntawm cov siv no yuav txawv thiab feem ntau yog tus tswv.
• Kev ua teb: Raws li cov nroj tsuag loj hlob promoter, L-leucine tau tshawb xyuas rau nws lub peev xwm los txhim kho cov qoob loo loj hlob thiab tawm los. Nws lub luag haujlwm hauv kev txhawb nqa protein synthesis hauv cov nroj tsuag ua rau nws muaj peev xwm biostimulant.

The manufacture of amino acids began with the hydrolysis of proteins in 1820. The extraction sequence is L-cystine, L-histidine, L-leucine, L-arginine. Xyoo 1908, Japanese Ikeda pom tias sodium glutamate yog cov tsw enhancer enhancer, pib keeb kwm kev lag luam ntawm cov amino acids. Xyoo 1957, Nyij Pooj pib siv cov kab mob me me glutamic acid, uas qhib tshooj tshiab hauv keeb kwm ntawm cov amino acid ntau lawm los ntawm microbial fermentation. Nyob rau hauv 1960s, Biosynthesis ntawm L-leucine thiab nws cov kev tswj hwm metabolic tau meej ib qho tom qab lwm tus. Qhov no muab lub hauv paus rau kev ua haujlwm rau kev hais plaub ntawm L-leucies ntau lawm los ntawm microbial fermentation thiab kev tsim covL-leucine hmoovlos ntawm enzyme.

Amino acid yog cov chaw ua haujlwm ntawm cov protein. Nyob rau hauv acidic tej yam kev mob, cov protein nrog cov ntsiab lus siab L-leucine yog hydrolyzed kom tau txais kev sib xyaw ntawm ntau cov amino acids. L-leucine khoom yog tau los ntawm kev sib cais, huv, kho kom zoo thiab lwm yam txheej txheem.

A. Strecker ,. Ammonia hydrolysis ntawm monohalogenated acid, Theem Hloov Cataly thiab lwm txoj hauv kev. Txawm hais tias lub hauv paus ntsiab lus ntawm synthesis yog qhov yooj yim thiab tus nqi yog qhov tsis txaus ntseeg, cov tshuaj tiv thaiv tsis siab, thiab qee txoj hauv kev koom nrog cov tshuaj lom neeg lom neeg. Leucine tau los ntawm tshuaj hluavtaws hluavtaws ntawm cov lecine dl. Txhawm rau kom tau txais cov khoom lag luam, kho qhov muag yog qhov yuav tsum tau daws.

Feem ntau, kev tsim cov l-leucine pauv mus rau ammonia los ntawm transaminase. Monoketoisohexoic acid ua l-leucine. Cov enzyme ntsig txog thiab Nadh yog kev sib luag ua txhaum rau daim nyias nyias, tso cai rau lub sijhawm qeeb los ntawm kev hla dhau ntawm daim nyias nyias thiab kev ua yeeb yam enzyme catalalyzed cov tshuaj tiv thaiv los tsim l-leucine. Xws li tam sim no 1981 tuaj yeem raug tshem tawm thiab muaj txiaj ntsig ntawm kev tshem tawm. Txoj hauv kev zoo tshaj plaws kom tau txais Mutant Strain suav cov hom phiaj khoom yog los daws cov qauv metabolic ntawm cov kab mob met. Ntau cov kev uas tau txais Mutant hom yog raws li hauv qab no:

(1) Kev yug me nyuam muaj txiaj ntsig zoo, txiav tawm lossis hloov pauv kom sib haum Metabolic Pathways;

(2) Kev tawm tsam tiv thaiv cov txheej txheem yuam kev kom zoo nkauj

(3) merants ntawm cell membrane kev xaiv tau xaiv los ua cov khoom lag luam uas zais cia hauv lub xov tooj ntawm lub cell tsis tuaj yeem ncav cuag cov tswv yim uas ua rau cov lus qhia. Daim ntawv thov cov genetic engineering thiab cov kev ua lag luam metabolic engineering los hloov cov roj micobial thiab ua rau lawv synthesize cov khoom lag luam hauv siab.

Xyoo 1987, gregere, tus kws tshawb fawb German, ntxiv ua ntej. Monoketo isocaproic acid yog siv los tsimL-leucine hmoov, thiab cov prefursor tau ntxiv rau hauv nruab nrab kab lis kev cai. Cov concentration ntawm monoketoisohexanoic acid yog 20g / l, condnebacterium gymeb Cov txheej txheem ntawm kev ua noj ua haus tuaj yeem siv rau ntxiv 32 g / l ntawm a-keto-isobexanoic acid, ferment rau 23 teev, thiab tsim 24 g / l ntawm l-leucine. Kev hloov dua siab tshiab ntawm monoketoisohexanoic acid rauL-leucine hmoovyog catalyzed los ntawm transaminase.

Tus Qauv Muag Channel Thiab Cov Tswv Yim
Muaj ntau yam kev muag tshuaj rau L-leucine hmoov, thiab lwm tus neeg tuaj yeem xaiv tus qauv muag uas tsim nyog raws lawv tus kheej qhov xwm txheej thiab kev lag luam xav tau. Cov hauv qab no yog cov ncauj lus kom ntxaws tshuaj xyuas ntawm cov qauv muag khoom tseem ceeb thiab cov tswv yim:
