Remark 700 | SHEET STRAND 4 OF SHEETS SMA AND SMB EXTENDS FROM 141 - 146. ACCORDING TO KABSCH AND SANDER ...SHEET STRAND 4 OF SHEETS SMA AND SMB EXTENDS FROM 141 - 146. ACCORDING TO KABSCH AND SANDER CRITERIA RESIDUE 147 CANNOT BE ATTRIBUTED AN EXTENDED CONFORMATION AND, THEREFORE, THE BETA STRAND IS INTERRUPTED AT THIS SITE. NEVERTHELESS THERE IS A HYDROGEN-BONDING INTERACTION BETWEEN RESIDUES CAL 5 AND GLY 148, AS IF THE BETA STRAND ACTUALLY CONTINUED FOR ONE RESIDUE AFTER 147. |
