prosite pattern to sequences

Hello,

Do you know how to convert a PROSITE pattern into actual list of sequences?

For example, for this pattern:
[EQ]-x-L-Y-[DEQST]-x(3,12)-[LIV]-[ST]-Y-x-R-[ST]-[DEQS]
I would like to convert to in set a of sequences.
.
The reason I’d like to have sequences is ow of UniProt Swiss-Prot in acceptance
