Question

below is the reaction and structure (monomer phosphate dehydrogenase. The enzyme is purified with FAD bound. NADH+H NAD B -monomer C- multimer Cytoplasmic glycerel 3-phosphate ?? Dihydrexyacetone phesphate Glyceral 3-phosphate glyceral 3-phosphate Cytoplasm E-FADH EFAD a) Which enzyme class does glycerol 3-phosphate dehydrogenase belong? Give the number and name for the class (b) How many domains does the monomer contain. Circle them (c) How many domains does the multimer contain. Circle them (d) Which level of protein structure does the multimer represent? e) What type of tertiary structure is glycerol 3-phosphate dehydrogenase?

Explanation / Answer

A) it belongs to thr family of oxidoreductases.

B) monomer contains 2 domains.

C) usually more than 2,it may be tertiary or may form hexameric unit.

D) crystalline form

eg- pyruvate kinase

It has three domains.

E) crystal structure
