Figure 2From: PePPER: a webserver for prediction of prokaryote promoter elements and regulonsPresence of regulon in query organisms by protein Blast. WalRK regulon genes of B. subtilis (a) and S. pneumoniae (b) were used to perform a protein Blast in order to examine whether a WalRK regulon might be present in Lactococci and Streptococci. Colors from light to dark blue are indicative of increasing protein similarity; for more details see the PePPER webserver.Back to article page
