O le malamalama i le metabolism o le microbial host e taua tele mo le atinaʻeina ma le faʻamalieina o faiga faʻavae biocatalytic atoa-cell, aua e faʻatonuina le gaosiga lelei.E moni lava lenei mea mo redox biocatalysis lea e fa'aogaina ai sela e fa'agaioia metabolically ona o le cofactor/cosubstrate gafatia toe fa'afo'isia i totonu o le fale talimalo.Recombinant Escherichia coli na faʻaaogaina mo le faʻateleina o le proline-4-hydroxylase (P4H), o se dioxygenase faʻapipiʻiina le hydroxylation o le free L-proline i le trans-4-hydroxy-L-proline ma le a-ketoglutarate (a-KG) e avea ma cosubstrate.I totonu o lenei sela atoa biocatalyst, carbon metabolism totonugalemu e maua ai le cosubstrate manaʻomia a-KG, faʻapipiʻi P4H biocatalytic faatinoga tuusao i carbon metabolism ma metabolic gaoioiga.E ala i le faʻaogaina o mea faigaluega faʻataʻitaʻi ma faʻaogaina o meaola, e pei o le metabolic engineering ma (13) C-metabolic flux analysis ((13) C-MFA), matou suʻesuʻeina ma faʻamatalaina faʻatusatusa le tali o le physiological, metabolic, ma le bioenergetic o le biocatalyst cell-cell. i le bioconversion fa'atatau ma fa'ailoa mai e mafai ona fa'agata fa'agata metabolic mo le fa'ainisinia ala fa'atatau. O le fa'aleagaina o le E. coli fa'aleagaina na fausia e ala i le tapeina o le gene putA e fa'ailoga proline dehydrogenase.O le biotransformations atoa-cell ma lenei mutant strain na taitai atu ai e le gata i le quantitative proline hydroxylation ae faapea foi i le faaluaina o le tulaga patino trans-4-L-hydroxyproline (hyp) faʻatulagaina, faʻatusatusa i le ituaiga vao.O le suʻesuʻeina o le carbon flux e ala i le ogatotonu o le metabolism o le mutant strain na faʻaalia ai o le faateleina o le manaʻoga o le a-KG mo le P4H e leʻi faʻaleleia ai le gaosiga o le a-KG, e faʻaalia ai le faʻatonutonuina o le taamilosaga TCA i lalo o tulaga suʻesuʻe.I le ituaiga vao, P4H synthesis ma catalysis na mafua ai le faʻaitiitia o le gaosiga o meaola.O le mea e malie ai, o le ΔputA strain na toe totogi ai le gau o le ATP ma le NADH e ala i le faʻaitiitia o le manaʻomia o le malosi i le faʻatusatusaina o le maualalo o le kulukose, nai lo le faʻateleina o le gaioiga o le TCA. ia folafola atu mo le gaosiga o le P4H catalysis e le gata i tulaga o le biotransformation yield, ae faʻatatau foi i fua faatatau mo le biotransformation ma le proline uptake ma le gaosiga o le hyp i luga o le puna malosi.O faʻaiʻuga e faʻaalia ai, i luga o le tuʻituʻi putA, o le tuʻufaʻatasia o le TCA-cycle i le proline hydroxylation e ala i le cosubstrate a-KG e avea ma mea taua e faʻalavelaveina ma faʻamoemoe e faʻaleleia atili le lelei o le biotransformations faʻalagolago i le a-KG.
