Here the residues which interact with the regulatory unit '''R''' are represent with halos and ball-and-stick. The residues from the catalytic unit's ''exon 1'' are labelled by residue index. Note that the last three residues from exon 1 (residues # 13-15) are the only amino acids from the first exon of the catalytic unit that were included in this crystal structure. |
