Remark 400 | COMPOUND THE PROTEINS NS2B (CHAIN A) AND NS3 (CHAIN B) ARE CONNECTED THROUGH A LINKER AGGGGSGGGG. | ||||||
Remark 999 | SEQUENCE THIS IS THE SEQUENCE OF THE LINKER BETWEEN CHAINS A AND B. RESIDUE NUMBERS 1 THROUGH 5 IN ... SEQUENCE THIS IS THE SEQUENCE OF THE LINKER BETWEEN CHAINS A AND B. RESIDUE NUMBERS 1 THROUGH 5 IN COORDINATES FOR CHAIN B ARE ARBITRARY, SINCE ONLY THESE FIVE RESIDUES WERE VISIBLE IN ELECTRON DENSITY. THE SEQUENCE ALIGNMENT OF THESE FIVE RESIDUES IS ALSO ARBITRARY AND IS BASED ONLY ON THE DISTANCE CRITERIA TO THE NEXT VISIBLE RESIDUES. |
