How many amino acids in myoglobin
WebMyoglobin is a relatively small protein that contains 150 amino acids. Mb is extremely compact, and consists of 75% alpha helical structure. The interior amino acids are almost entirely nonpolar. The only polar amino acids found completely buried are the two His (proximal and distal) found at the active site of dioxygen binding. WebMar 5, 2024 · It is dependent upon at least a dipeptide structure (see above), thus, contaminating amino acids will not contribute to the 550nm absorption The binding depends upon the peptide backbone nitrogen and not the side chain functional group. Thus, the binding is independent of sequence
