Fahamka dheef-shiid kiimikaad ee martida loo yahay microbial waxay lagama maarmaan u tahay horumarinta iyo hagaajinta hababka biocatalytic-ku-saleysan ee unugga oo dhan, maadaama ay farayso hufnaanta wax-soo-saarka.Tani waxay si gaar ah run ugu tahay biocatalysis redox halkaasoo unugyada dheef-shiid kiimikaadka firfircooni ay ka shaqeeyaan sababtoo ah awoodda dib-u-soo-nooleynta ee cofactor / cosubstrate ee ku jirta martida loo yahay.Dib-u-soo-celinta Escherichia coli waxaa loo isticmaalay soo saarista proline-4-hydroxylase (P4H), dioxygenase kicinta hydroxylation ee L-proline bilaash ah trans-4-hydroxy-L-proline oo leh a-ketoglutarate (a-KG) sida cosubstrate.Qaybtan biocatalyst-unug dhan, dheef-shiid kiimikaad dhexe wuxuu bixiyaa cosubstrate-ka loo baahan yahay a-KG, isku-xidhka waxqabadka biocatalytic P4H si toos ah dheef-shiid kiimikaadka iyo dhaqdhaqaaqa dheef-shiid kiimikaadka.Anagoo adeegsanayna aaladaha bayoolojiga tijaabada ah iyo xisaabinta labadaba, sida injineernimada dheef-shiid kiimikaadka iyo (13) Falanqaynta qulqulka dheef-shiid kiimikaadka C-((13)C-MFA), waxaanu baarnay oo aan tiro ahaan u sharaxnay falcelinta jireed, dheef-shiid kiimikaad, iyo bioenergetic ee biocatalyst-unug dhan Si loo beddelo bioconversion-ka la beegsaday oo la aqoonsaday caqabadaha dheef-shiid kiimikaad ee suurtagalka ah ee injineernimada dariiqa macquulka ah ee dheeraadka ah. Cadaadiska proline-la'aanta E. koli waxaa la dhisay iyadoo la tirtiray hidda-wadaha putA ee codeynaya proline dehydrogenase.Biotransformations biotransformations ee unug dhan oo leh nooca mutant-ka ah ayaa keenay kaliya ma aha in la qiyaaso proline hydroxylation laakiin sidoo kale labanlaabida heerka samaynta trans-4-L-hydroxyproline (hyp), marka loo eego nooca duurjoogta ah.Falanqaynta qulqulka kaarboonka iyada oo loo marayo dheef-shiid kiimikaad dhexe ee mutant mutant ayaa shaaca ka qaaday in kororka baahida a-KG ee waxqabadka P4H aysan kor u qaadin qulqulka a-KG, taas oo muujinaysa hawlgal wareeg ah oo TCA ah oo si adag loo habeeyey iyada oo la raacayo shuruudaha la darsay.Cadaadiska nooca duurjoogta ah, isku-dhafka P4H iyo catalysis ayaa sababay hoos u dhaca wax-soo-saarka noole.Waxa xiisaha lihi leh, cadaadiska ΔputA waxa kale oo uu magdhabay khasaaraha ATP iyo NADH ee la xidhiidha iyada oo la dhimay baahida tamarta dayactirka ee heerarka qaadashada gulukooska ee hooseeya, halkii la kordhin lahaa waxqabadka TCA. Noqo mid u ballan qaadaya catalysis wax soo saar leh ee P4H ma aha oo kaliya marka la eego wax-soosaarka biotransformation, laakiin sidoo kale ku saabsan heerarka biotransformation iyo qaadashada proline iyo dhalidda hyp ee isha tamarta.Natiijooyinku waxay muujinayaan in, marka la garaaco garaaca, isku-xidhka wareegga TCA-ga ee proline hydroxylation iyada oo loo marayo cosubstrate a-KG waxay noqotaa cunsur muhiim ah oo xannibaya iyo bartilmaameed si loo sii wanaajiyo waxtarka a-KG-ku-tiirsanaanta biotransformations.
