Question
Chapter 10, Problem 8E
Summary Introduction
To explain: The amino acids that are particularly abundant at the entrance of a porin that is specific for phosphate ions.
Concept introduction: Porin is a trans-membrane protein that allows the molecules or ions to pass across the membrane. In general, the size of the central aqueous channel and the residues that form at the trans-membrane will determine the type of substance that is able to pass through it.

What is the importance of glutamic acid in the metabolism of nitrogen from amino acids? (we know therole; it’s used to remove the nitrogen from amino acids so that the remaining carbon skeleton can bebroken down by the “usual” pathways, but what is the important, unique role that only glutamicacid/glutamate can do?)
