Chapter 25, Problem 25P
Interpretation Introduction

Interpretation:

The standard free energy of the binding of methotrexate using the given three proteins and the decrease in BE due to each mutation needs to be determined.

Concept introduction:

Proteins are chains of amino acid joined with polypeptide bonds. Each protein has an active site in its native functional structure. In this active site, few amino acids interact with the ligands. Mutation in these amino acids can lead to functional change of the protein.

Just Arrange.  The enzyme serine hydroxymethyltransferase (SHMT) requires pyridoxal phosphate (PLP) as a cofactor. Arrange the steps of the likely mechanism for SHMT‑catalyzed serine degradation (producing glycine and N5,N10‑methylenetetrahydrofolate)
Draw the structure. Saccharide X occurs in the roots of several species of plants. Deduce the structure of saccharide x from the following data: 1. Acidic hydrolysis of 1 mol of stachyose yields 2 mol of D-galactose, 1 mol of D-glucose, and 1 mol of D-fructose. 2. Stachyose is a nonreducing sugar. 3. Treating stachyose with an a-galactosidase produces a mixture containing D-galactose, sucrose, and a nonreducing trisaccharide called raffinose. 4. Acidic hydrolysis of raffinose gives D-glucose, D-fructose, and D-galactose. Treating raffinose with an a-galactosidase yields D-galactose and sucrose. Treating raffinose with invertase (an enzyme that hydrolyzes sucrose) yields fructose and melibiose 5. Methylation of saccharide x followed by hydrolysis yields 2,3,4,6-tetra-O-methyl-D-galactose, 2,3,4-tri-0-methyl-D-galactose, 2,3,4-tri-O-methyl-D-glucose, and 1,3,4,6-tetra-O-methyl-D-fructose.
Synthetic stoichiometries. What is the stoichiometry of the synthesis of... (a) ribose 5-phosphate from glucose 6- phosphate without the concomitant generation of NADPH? (b) NADPH from glucose 6-phosphate without the concomitant formation of pentose sugars?
