In the Sequences section sequences of macromolecules (in the "actual unit") are presented together with information on secondary structure (for proteins) and information of bonds between protein and nucleic acid residues.
Sequences are hidden by default, to visualize a sequence click "SHOW" button:
The protein chain 'A' is shown on image above, where:
Serial number is a serial number of a residue.
PDB number is a number of a residue in the PDB file.
Sequence is the sequence of the macromolecule (chain A) in one-letter format.
Secondary str. is the secondary structure of the macromolecule (for protein chains only!), where
H is for alpha helix
E is for beta strand
C is for coil
T is for turn
G is for 310-helix
Residue type is a type of a residue. Grey means protein, orange means deoxyribonucleotide, purple means ribonucleotide
Hbonds is a number of hydrogen bonds with nucleic acid (for protein chains) or with protein (for nucleic chains) formed by a residue.
Water bridges is a number of water bridges.
Hydrophobic clusters is a serial number of a hydrophobic cluster in which a residue is involved.
