#dr ⇒ Object Also known as: sp_xref

DR Cross-references to SWISS-PROT (>=0 per entry)

DR   AC_NB, ENTRY_NAME, C; AC_NB, ENTRY_NAME, C; AC_NB, ENTRY_NAME, C;

• ‘AC_NB’ is the SWISS-PROT primary accession number of the entry to which reference is being made.

• ‘ENTRY_NAME’ is the SWISS-PROT entry name.

• ‘C’ is a one character flag that can be one of the following:

T For a true positive. N For a false negative; a sequence which belongs to the set under

consideration, but which has not been picked up by the pattern or
profile.

P For a ‘potential’ hit; a sequence that belongs to the set under

consideration, but which was not picked up because the region(s) that
are used as a 'fingerprint' (pattern or profile) is not yet available
in the data bank (partial sequence).

? For an unknown; a sequence which possibly could belong to the set under

consideration.

F For a false positive; a sequence which does not belong to the set in

consideration.
