来自荧光假单胞菌 Biovar I. (BAL, EC 4.1.2.38) 的苯甲醛裂解酶是一种用于手性 α-羟基酮有机合成的多功能催化剂。为了快速评估酶活性,需要直接分光光度测定。在此,提出了一种基于紫外线吸收的新的稳健且易于操作的测定方法。所开发的检测方法基于 2-糠醛中 α-羟基酮 (R)-2,2'-糠醛的连接。方便的浓度工作范围有助于直接监测产品的稳健测定,最大限度地减少与低浓度相关的实验。
Benzaldehyde lyase from Pseudomonas fluorescens Biovar I. (BAL, EC 4.1.2.38) is a versatile catalyst for the organic synthesis of chiral α-hydroxy ketones. To allow fast assessment of enzyme activity, a direct spectrophotometric assay is desirable. Here, a new robust and easy-to-handle assay based on UV absorption is presented. The assay developed is based on the ligation of the α-hydroxy ketone (R)-2,2′-furoin from 2-furaldehyde. A robust assay with direct monitoring of the product is facilitated with a convenient concentration working range minimising experimental associated with low concentrations.
