question :
Information about an enzyme is often stored in its name. Consider the names of the following enzymes. What information do you know about these enzymes from their names (for instance, do you know the enzyme’s substrates, products, locations or modes of action)? (2 points each)
a)Golgi mannosidase
b) N-acetylglucosamine transferase
c) NADH dehydrogenase complex
d) Ribulose bisphosphate carboxylase
e )Propose a name for a novel enzyme that breaks down oligosaccharides inside lysosomes. (there is no wrong answer to this question!)
please answer all parts a-e as this is entirely one question. thank you!
Explanation / Answer
a) Golgi mannosidase : As its name suggest, it is the mannose hydrolyzing enzyme and it is present in Golgi. And there are two types of mannosidase, alpha mannosidase cleave alpha form of mannose and beta mannosidase cleave terminal, non-reducing beta-D-mannose residues in beta-D-mannosides.
b) N-acetylglucosamine transferase : Transferase catalyze the transfer of specific functional group from donor to acceptor. N-acetylglucosamine is a carbohydrate moeity added to serine or threonine residues of a protein which results in protein glycosylation.
c) NADH dehydrogenase complex : Dehydrogenases generally transfer electrons from the substrate to an electron carrier. If the electron carrier is NADH it is called NADH dehydrogenase. The complex denotes that it is an enzyme of the respiratory chain which is involved in H+ or Na+ translocation so it belongs to translocating NADH Dehydrogenase (NDH) Family.
d) Ribulose bisphosphate carboxylase : It catalyzes the carboxylation of ribulose-1,5-bisphosphate.
e) Lysosomal glucosidase breaks down oligosaccharides like glycogen inside lysosomes.
