Question

Cells can make certain oligopeptides using conventional enzymes rather than mRNA-directed translation by a ribosome. Draw the product of the reaction catalyzed by L-glutamate: L-cysteine gamma-ligase

$\left(\mathbf{\gamma }\mathbf{-}\mathbf{glutamylcysteinesynthetase}\right)$

Short answer

The product obtained in the reaction is:

Step-by-step solution

Enzyme

Enzyme constitutes a catalytic molecule that enhances the rate of any chemical reaction without being used up in the reaction. It can be any protein molecule or in some cases, it is an RNA molecule. An enzyme links with the substrate or reactant of a particular reaction and produces the end products.

Draw the product of the reaction catalyzed by L-glutamate

$\mathrm{y}-\mathrm{glutamylcysteine}\mathrm{synthetase}$or glutamate-cysteine ligase (GCL) is the enzyme that participates in the glutathione synthesis pathway. The reaction catalyses by GCL are:

$\text{L - glutamate + L - cysteine + ATP}\rightleftharpoons {\text{gamma - glutamylcysteine + ADP +P}}_{\text{i}}$

The structure of gamma-glutamylcysteine is:
