Branches of glycogen that are 2–3 residues long
« on: October 29, 2023, 10:41:40 AM »
Hi, I know that the debranching enzyme can act on the branches that are 4 residues long and connect via 1,6 bond to a chain. What if there were a branch that is 2 or 3 residues long? Could it act on them? What would happen?

Also, it is said that the glycogen phosphorylase stops working 4 residues before 1,6 bond. Does this include both types of branches, I mean "the one which offers its 1st carbon in the 1,6 bond" as well as "the one which offers its 6th carbon"?

I don't know the answer to your question.  My suggestion is to use PubMed as a search engine for the biochemical literature.  I might use "glycogen debranching enzyme" as a search term, and I might restrict myself to review articles.
