Summary Introduction

To review:

The inference drawn from the fact that different vertebrate species have variations in the amino acid sequences of insulin enzyme and the reason behind the presence of amino acid sequences at only certain positions.

Introduction:

The activity of any enzyme depends upon the presence of specific amino acids in its structure. For example, in insulin enzyme, the hydrophobic amino acids are present that helps the enzyme to bind to its substrate.

The 20 standard amino acids may undergo chemical transformations to form  biologically active amino acids:   (a) Give three (3) modifications that produced three (3) biologically active molecules.   (b) For each in (a) state their corresponding physiological role in the mammalian  system.
The death cap mushroom (Amanita phalloides) is considered one of the world’s deadliest mushrooms. The toxicity of the Amanita species is due to the presence of two groups of toxins known as amatoxins and phallotoxins, both made of multiple cyclic peptide chains (circular sequence of bonds). Do some research about the death cap and answer: What makes the Amanita phalloides toxins so harmful that even one cap can kill an adult?
Why is the variation across different species not distributed uniformly throughout the molecule?  What is your best explanation for the very limited variation within the marked homeobox domain? Specific residues at positions 129 and 228 (boxed) are associated with beak shape in Geospiza finches on the Galapagos Islands. Choose one of these sites, and propose a hypothesis for why a change results in a significant alteration in beak shape.
