PDB Specification

Overview

SHEET records are used to identify the position of sheets in the molecule. Sheets are both named and numbered. The residues where the sheet begins and ends are noted.

Record Format

COLUMNS	DATA TYPE	FIELD	DEFINITION
1 - 6	Record name	“SHEET “
8 - 10	Integer	strand	Strand number which starts at 1 for each
			strand within a sheet and increases by one.
12 - 14	LString(3)	sheetID	Sheet identifier.
15 - 16	Integer	numStrands	Number of strands in sheet.
18 - 20	Residue name	initResName	Residue name of initial residue.
22	Character	initChainID	Chain identifier of initial residue
			in strand.
23 - 26	Integer	initSeqNum	Sequence number of initial residue
			in strand.
27	AChar	initICode	Insertion code of initial residue
			in strand.
29 - 31	Residue name	endResName	Residue name of terminal residue.
33	Character	endChainID	Chain identifier of terminal residue.
34 - 37	Integer	endSeqNum	Sequence number of terminal residue.
38	AChar	endICode	Insertion code of terminal residue.
39 - 40	Integer	sense	Sense of strand with respect to previous
			strand in the sheet. 0 if first strand,
			1 if parallel,and -1 if anti-parallel.
42 - 45	Atom	curAtom	Registration. Atom name in current strand.
46 - 48	Residue name	curResName	Registration. Residue name in current strand
50	Character	curChainId	Registration. Chain identifier in
			current strand.
51 - 54	Integer	curResSeq	Registration. Residue sequence number
			in current strand.
55	AChar	curICode	Registration. Insertion code in
			current strand.
57 - 60	Atom	prevAtom	Registration. Atom name in previous strand.
61 - 63	Residue name	prevResName	Registration. Residue name in
			previous strand.
65	Character	prevChainId	Registration. Chain identifier in
			previous strand.
66 - 69	Integer	prevResSeq	Registration. Residue sequence number
			in previous strand.
70	AChar	prevICode	Registration. Insertion code in previous strand.

Details

• The initial residue for a strand is its N-terminus. Strand registration information is provided in columns 39 - 70. Strands are listed starting with one edge of the sheet and continuing to the spatially adjacent strand.
• The sense in columns 39 - 40 indicates whether strand n is parallel (sense = 1) or anti-parallel (sense = -1) to strand n-1. Sense is equal to zero (0) for the first strand of a sheet.
• The registration (columns 42 - 70) of strand n to strand n-1 may be specified by one hydrogen bond between each such pair of strands. This is done by providing the hydrogen bonding between the current and previous strands. No register information should be provided for the first strand.
• Split strands, or strands with two or more runs of residues from discontinuous parts of the amino acid sequence, are explicitly listed. Detail description can be included in the REMARK 700 .
