Abstract
This work describes a new simultaneous on-flow dual parallel enzyme assay based on immobilized enzyme reactors (ICERs) with mass spectrometry detection. The novelty of this work relies on the fact that two different enzymes can be screened at the same time with only one single sample injection and in less than 6 min. The system consisted of two immobilized capillary enzyme reactors (ICERs). More specifically, the ICERs comprised two different enzymes that were accommodated in parallel and were placed between a liquid chromatography (LC) system and a mass spectrometer (MS). The resulting system could be adapted to other types of enzyme reactors with different supports. All the elements in the system were interfaced by means of two 10-port/two-position switching valves. Different tubing dimensions allowed us to monitor the activity of each enzyme independently during the same analysis. Acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) bioreactors were chosen as proof of concept. Acetylcholine (ACh) was used as substrate; the area of its protonated enzymatic hydrolysis product ion, choline, [M+H]+m/z 104.0, was monitored in the presence and absence of the standard cholinesterase inhibitor galantamine. This method proved to be an interesting tool for fast, simultaneous, and independent label-free dual enzyme inhibitor assay.

Anal Biochem 2018; 559:62-70. [PMID: 30165045 DOI: 10.1016/j.ab.2018.08.022] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2018] [Revised: 08/23/2018] [Accepted: 08/24/2018] [Indexed: 12/19/2022]
Abstract
Transglutaminase 2 (TGase2) kinase has emerged as an important regulator of apoptosis as well as chromatin structure and function; however, details about the pathophysiological functions of TGase2 kinase have been limited because of the lack of a suitable activity assay for systematic investigation of TGase2 kinase regulation in a high-throughput manner. Thus, we developed a novel on-chip TGase2 kinase activity assay using a cysteine-modified insulin-like growth factor-binding protein-3-derived peptide (CMI peptide) on an array platform. This peptide array-based activity assay was reproducible, with a detection limit of 2.127 μg/ml. We successfully applied this assay to investigate the effects of thiol-reactive compounds and divalent cations on TGase2 kinase by determining the half maximal inhibitory concentrations (IC50). Thiol-reactive compounds inhibited TGase2 kinase activity in a concentration-dependent manner, with IC50 values ranging from 0.125 to 5.550 mM. Divalent metal cations also showed a concentration-dependent inhibition, with IC50 values ranging from 0.005 to 1.937 mM; however, Ca2+ had no effect on TGase2 kinase activity. Thus, this novel kinase activity assay using the CMI peptide array described here is suitable for systematic investigation of TGase2 kinase regulation and may be useful for investigating the roles of TGase2 kinase in pathogenesis of kinase-mediated diseases.
