Summary Introduction
To review:
The way in which a protein A made by Staphylococcus aureus can be exploited in immunoassays.
Introduction:
Staphylococcus aureus surface protein A is a 42 Da (Dalton) protein, which is composed of 2271 amino acids and belongs to serine-rich repeat proteins family. Protein A is encoded by the spa gene. It is used in research because of its ability to bind with the immunoglobulin. It is composed of five immunoglobulin domain that folds into a three-helix bundle. It binds to the heavy chain that is present in the Fc (fragment crystallizable) region of most of the most immunoglobulins.

The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. 18 carbons fatty acids 12 carbons glycerol . Glycerol is broken down to glyceraldehyde 3-phosphate, a glycolysis intermediate via the following pathway shown in the figure below. Notice this process costs one ATP but generates one FADH2.
