Application

Astec® CHIRALDEX™ G-TA（2，6-二-O-戊基-3-三氟乙酰基-γ-环糊精）衍生的环糊精手性固定相可用于毛细管气相色谱，用于从 7 种外消旋亚磺酸酯中分离四种异构体。将其用于通过分析海洋细菌 Erythrobacter litoralis HTCC2594 的开放阅读框（ORF）鉴定的三种环氧化物水解酶的克隆和表征的实验研究。它还用于 HPLC 和 GC 分析环氧化物的转化过程中，环氧化物水解酶从农杆菌放射杆菌（EchA）的对映选择性（使用易错 PCR 和 DNA 改组）。

  • -10 °C 至 180 °C 等温和程序的

General description

Astec® CHIRALDEX G-TA 是第 1 组 CSP（表面相互作用，复合衍生物）的首选。该阶段已被证明是制药行业最广泛选择的阶段，特别是在临床试验的各个阶段中手性中间体和药物研究的分析。在没有包含机制的情况下发生分离，并且通常比大多数手性固定相更快且更有效。G-TA 也被用于分离母体药物对映体及其代谢物。G-TA 对含氧分析物的选择性最高，如醇、二醇和多元醇，作为游离醇和酰基衍生物；胺类作为酰基衍生物；氨基醇、卤素（Cl> Br> F）、氨基酸、羟基酸、内酯、呋喃和吡喃。它对卤化物也具有高选择性。

Previously, we reported that ten strains belonging to Erythrobacter showed epoxide hydrolase (EHase) activities toward various epoxide substrates. Three genes encoding putative EHases were identified by analyzing open reading frames of Erythrobacter litoralis HTCC2594. Despite low similarities to reported EHases

The enantioselectivity of epoxide hydrolase from Agrobacterium radiobacter (EchA) was improved using error-prone PCR and DNA shuffling. An agar plate assay was used to screen the mutant libraries for activity. Screening for improved enantioselectivity was subsequently done by spectrophotometric progress

Enzyme stability is an important parameter in biocatalytic applications, and there is a strong need for efficient methods to generate robust enzymes. We investigated whether stabilizing disulfide bonds can be computationally designed based on a model structure. In our approach
