How to parse a string (by a "new" markup) with R ?

For example, let's say we have the following two variables:
Seq <-
"GCCTCGATAGCTCAGTTGGGAGAGCGTACGACTGAAGATCGTAAGGtCACCAGTTCGATCCTGGTTCGGGGCA"
Str <-
">>>>>>>..>>>>........<<<<.>>>>>.......<<<<<.....>>>>>.......<<<<<<<<<<<<."
Say that I want to parse "Seq"...

Str<- ">>>>>>>..>>>>........<<<<.>>>>>.......<<<<<.....>>>>>.......<<<<<<<<<<<<."
x<-splitSeq(Seq,Str)
