- * Potexviruses and carlaviruses coat protein signature *
- ********************************************************
-
- Potexviruses and carlaviruses are plant-infecting viruses whose genome consist
- of a single-stranded RNA molecule encapsided in a coat protein. The genome of
- many potexviruses is known and their coat protein sequence has been shown to
- be rather well conserved [1]. The same observation applies to the coat protein
- of a variety of carlaviruses whose sequences are related to those of
- potexviruses [2,3]. The coat proteins of potexviruses and of carlaviruses
- contain from 190 to 300 amino acid residues.
-
- The best conserved region of these coat proteins is located in the central
- part and can be used as a signature pattern.
-
- -Consensus pattern: [RK]-[FY]-A-[GAP]-F-D-x-F-x(2)-V-x(3)-[GAST](2)
- -Sequences known to belong to this class detected by the pattern: ALL, except
- for the coat protein of Foxtail Mosaic Virus (FMV).
- -Other sequence(s) detected in SWISS-PROT: NONE.
- -Last update: October 1993 / Pattern and text revised.
