Overview

HELIX records are used to identify the position of helices in the molecule. Helices are named, numbered, and classified by type. The residues where the helix begins and ends are noted, as well as the total length.

Record Format

COLUMNS	DATA TYPE	FIELD	DEFINITION
1 - 6	Record name	“HELIX “
8 - 10	Integer	serNum	Serial number of the helix. This starts
			at 1 and increases incrementally.
12 - 14	LString(3)	helixID	Helix identifier. In addition to a serial
			number, each helix is given an
			alphanumeric character helix identifier.
16 - 18	Residue name	initResName	Name of the initial residue.
20	Character	initChainID	Chain identifier for the chain containing
			this helix.
22 - 25	Integer	initSeqNum	Sequence number of the initial residue.
26	AChar	initICode	Insertion code of the initial residue.
28 - 30	Residue name	endResName	Name of the terminal residue of the helix.
32	Character	endChainID	Chain identifier for the chain containing
			this helix.
34 - 37	Integer	endSeqNum	Sequence number of the terminal residue.
38	AChar	endICode	Insertion code of the terminal residue.
39 - 40	Integer	helixClass	Helix class (see below).
41 - 70	String	comment	Comment about this helix.
72 - 76	Integer	length	Length of this helix.

Details

Additional HELIX records with different serial numbers and identifiers occur if more than one helix is present. The initial residue of the helix is the N-terminal residue. Helices are classified as follows:

| | CLASS NUMBER |

TYPE OF HELIX	(COLUMNS 39 - 40)
Right-handed alpha (default)	1
Right-handed omega	2
Right-handed pi	3
Right-handed gamma	4
Right-handed 3 - 10	5
Left-handed alpha	6
Left-handed omega	7
Left-handed gamma	8
2 - 7 ribbon/helix	9
Polyproline	10
