117153-55-6 Usage

General Description

4-(Trifluoromethyl)umbelliferyl-beta-D-galactopyranoside is a chemical compound that is often used as a substrate in the measurement of beta-galactosidase activity. It is a fluorogenic substrate, meaning that it produces a fluorescent product when acted upon by the enzyme. 4-(TRIFLUOROMETHYL)UMBELLIFERYL-BETA-D-GALACTOPYRANOSIDE is commonly used in biochemical and medical research to study the activity of beta-galactosidase, an enzyme that hydrolyzes beta-galactosidic bonds in lactose and other substrates. The trifluoromethyl group enhances the fluorescence of the compound, making it a useful tool for detecting and quantifying the activity of beta-galactosidase in various biological samples.

Check Digit Verification of cas no

The CAS Registry Mumber 117153-55-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,1,5 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 117153-55:
(8*1)+(7*1)+(6*7)+(5*1)+(4*5)+(3*3)+(2*5)+(1*5)=106
106 % 10 = 6
So 117153-55-6 is a valid CAS Registry Number.

Glycosyl Cations versus Allylic Cations in Spontaneous and Enzymatic Hydrolysis

Danby, Phillip M.,Withers, Stephen G.

supporting information, p. 10629 - 10632 (2017/08/15)

Enzymatic prenyl and glycosyl transfer are seemingly unrelated reactions that yield molecules and protein modifications with disparate biological functions. However, both reactions employ diphosphate-activated donors and each proceed via cationic species: allylic cations and oxocarbenium ions, respectively. In this study, we explore the relationship between these processes by preparing valienyl ethers to serve as glycoside mimics that are capable of allylic rather than oxocarbenium cation stabilization. Rate constants for spontaneous hydrolysis of aryl glycosides and their analogous valienyl ethers were found to be almost identical, as were the corresponding activation enthalpies and entropies. This close similarity extended to the associated secondary kinetic isotope effects (KIEs), indicating very similar transition state stabilities and structures. Screening a library of over 100 β-glucosidases identified a number of enzymes that catalyze hydrolysis of these valienyl ethers with kcat values up to 20 s-1. Detailed analysis of one such enzyme showed that ether hydrolysis occurs via the analogous mechanisms found for glycosides, and through a very similar transition state. This suggests that the generally lower rates of enzymatic cleavage of the cyclitol ethers reflects evolutionary specialization of these enzymes toward glycosides rather than inherent reactivity differences.
