unctions, glycosyltransferases are identified to become involved in a multitude of biological processes, like cell ell communication, immune responses [4], cell signaling and epigenetic regulation of gene expression [7,8], and plant- and bacterial-cell wall biosynthesis [9,10]. As a corollary, the disruption of those biological processes as a consequence of abnormal glycosyltransferase activity or expression can have a detrimental impact on thePublisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations.Copyright: 2021 by the authors.

Glycosyltransferase inhibitors are getting created for the remedy of these ailments, also as metabolic diseases, which include Morbus Gaucher, a lysosomal storage illness characterized by an accumulation of glucocerebrosides in multiple organs as a consequence of dysfunctional downstream degradation machinery (glucocerebrosidase), causing detrimental neurological and muscular symptoms [13,14]. The first-line therapy for Gaucher is Glucocerebrosidase enzyme replacement therapy, which can be a burdensome treatment due to the routine injections that the sufferers undertake. Glucosylceramide synthase (GCS) is definitely the GT that produces these glucocerebrosides employing UDP-Glucose as a donor and ceramides as acceptor substrates. An option to the intense enzyme replacement therapy, the identification of a tiny molecule inhibitor of GCS that could lessen the glucosylceramide product within the brain and be administered orally, could be a useful remedy of Gaucher disease (Substrate reduction therapy) [15]. Due to the value of this class of enzymes, there’s a need to develop bioassays to study their activity and their regulation or determine chemical compounds that modulate their activity. Currently, measuring glycosyltransferase activity relies on conventional strategies, including the chromatographic separation of substrate and item or the detection of a radiolabeled solution. Though these assays have proved to be useful when it comes to sensitivity and precision, they are cumbersome as they demand washing actions and separation on the glycosylated product for analysis and are certainly not conveniently configured for fast IL-12 Inhibitor Accession screening [16]. Alternatively, a number of assay technologies not requiring the use of radiochemicals were developed in the final two decades [17]. A number of them are fluorescence-based assays that detect the nucleoside diphosphate applying either fluorescent chemosensors [18,19] or fluorescent tracers combined with immunodetection [20]. These assays possess the advantage of getting universal for all GTs that release the detected nucleotide. However, specificity towards the nucleotide versus the nucleotide-sugar substrate can generate higher background; thus, decreasing the sensitivity as well as the accuracy of the assay. In addition, chemosensors’ availability and synthesis price could limit their widespread acceptance [17]. Other universal nucleotide detection assays relying on the enzyme-coupled generation of fluorescence or absorbance were also developed for GT activity measurement [21,22]. The fluorescent GT assays rel
