Staphylokinase (SAK; also known as staphylococcal fibrinolysin or MĂŒller’s factor) is a protein produced by Staphylococcus aureus. It contains 136 amino acid residues and has a molecular mass of 15kDa. Synthesis of staphylokinase occurs in late exponential phase. It is similar to strep
Proline and a few other notes
Proline (symbol Pro or P) is an organic acid classed as a proteinogenic amino acid (used in the biosynthesis of proteins), although it does not contain the amino group -NH2 but is rather a secondary amine. The secondary amine nitrogen is in
Serine
Serine (symbol Ser or S) is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated âNH+3 form under biological conditions), a carboxyl group (which is in the deprotonated âCOOâ form under biological conditions), a
