Stable arrangements of amino acid residues giving rise to recurring structural patterns
Tertiary Structure
All the aspects of three dimensional folding of a polypeptide
Quaternary Structure
WHen a protein has two or more polypeptide subunits , their arrangement in space is referred to as quaternary structure.
Polymorphic
Having amino acid sequence variations in the human population.
Edman Degradation
This procedure labels and removes only the amino-terminal residue from a peptide, leaving all other peptide bonds intact. Is used to sequence a polypeptide up to 50 aa's long.
Sequenator
Is a machine where an Edman degradation is carried out. It mixes the reagents in the proper proportions, separates the products, identifies them and records the results.
Sanger Method
Is a procedure used to identify the N-terminal amino acid residue.
Proteases
Are Enzymes which catalyze the hydrolytic cleavage of peptide bonds.
Proteome
Entire Protein complement encoded by an organisims DNA.
