Presence 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.
