3of5 web interface. Three different patterns were entered to be searched for in the sequence of the nucleoplasmin protein of Xenopus laevis [Swiss-Prot:P05221]. Header lines starting with ">>" indicate grouped patterns as feature of the "FASTA grouped" mode. Two posttranslational modification patterns (PKC and Amidation) are thus combined to the group "Posttransl. motif". A second group "Localization motif" contains one pattern (nucleoplasmin NLS [Prosite:PS00015]) in the example. The pattern format is selected by activating the appropriate check box on top of the pattern window. The sequence that shall be investigated in pattern matching is copied into the sequence window, either in FASTA, multiple FASTA, or simple text formats. An output in XML is optional.
