Whakaahuatanga Poto:

Mo te transaminase

ATA mai i SyncoZymes: E 66 nga momo hua enzyme ATA (Tau hei ES-ATA-101~ES-ATA-166) i hangaia e SyncoZymes.He taputapu whai hua te SZ-ATA ki te whakakoi i te whakahiato-a-rohe me te stereoselective synthesis o chiral amines, waikawa amino me o raatau hua mai i nga momo ketoacids aliphatic me te kakara, aldehydes, ketones me te ketoses.

Mo te transaminase:

Enzymes: He whakakōkī koiora macromolecular, he pūmua te nuinga o ngā whākōkī.

Transaminases: He karaehe ngongo e whakakorikori ana i te whakawhiti i waenga i nga waikawa amino me nga waikawa keto.Ko nga transaminases he whākōkī koiora matua i roto i te whakahiato hangarite me te taumira racemic o nga amine chiral.
Ka taea te wehewehea Aminotransferase ki nga akomanga e wha i runga i te raupapa me te hanganga: Ⅰ, Ⅱ, Ⅲ me Ⅳ.Ko nga ω-aminotransferases kei roto i te karaehe II transaminases, ka whakamahia i roto i te whakarite o nga amine kira me nga waikawa amino koretake, penei i te waikawa β-amino.

ω-aminotransferases: I te nuinga o nga wa, ko te ω-transaminase e tohu ana ki te karaehe o nga enzymes, ko nga tauhohenga whakawhiti haukini whakakata kaore he waikawa α-amino hei tïpako, hua ranei.

Hangahanga catalytic:

Transaminase ATA1

Mōhiohio Hua:

Nga Enzymes Waehere Hua Waehere Hua
Te paura Enzyme ES-ATA-101~ ES-ATA-165 he huinga 65 ω-Transaminases, 50 mg ia 65 mea * 50mg / mea, etahi atu rahinga ranei
Kete Tirohanga (SynKit) ES-ATA-6500 he huinga o 65 ω-Transaminase, 1 mg ia 65 mea * 1mg / mea

Nga painga o te ATA mo te huringa koiora:

★ motuhake tïpako High.
★ He kaha te whiriwhiringa o te chiral.
★ te kaha o te hurihanga teitei.
★ He iti ake nga hua.
★ Nga tikanga tauhohenga ngawari.
★ He pai te taiao.

Nga tohutohu mo te whakamahi:

➢ Me mahi te tirotiro i te haukini mo nga taputapu motuhake na te mea he motuhake te taputapu, me te tiki i tetahi whaariki e whakakorikori ana i te tïpako i whäia me te whai hua whakatiki pai rawa atu.
➢ Kaua rawa e pa atu ki nga ahuatanga kino penei: te pāmahana teitei, te pH teitei/iti me te whakarewa pararopi me te kukū teitei.
➢ Ko te tikanga, me whakauru te punaha tauhohenga he tïpako, he wairewa buffer, he kaituku amino (pënei i te waikawa amino me te 1-phenyl ethylamine) ranei te kaiwhakawhiwhi (pënei i te waikawa keto), te coenzyme (PLP), te ngohe (pënei i te DMSO).
➢ Me whakauru te ATA whakamutunga ki te punaha tauhohenga, i muri i te whakatikanga o te pH me te pāmahana ki te ahua o te tauhohenga.
➢ Ko nga momo ATA katoa he rerekee nga tikanga tauhohenga tino pai, no reira me ako takitahi ia o raatau.
