WebFeb 23, 2015 · Thiocillins Are Partially Responsible for B. cereus’ Ability to Induce B. subtilis Biofilm Matrix. Using a mutant of B. cereus that does not contain the structural genes required to produce the thiocillins (Δ tclE-H ) ( 32 ), we examined the ability of wild-type (WT) and Δ tclE-H B. cereus to induce P tapA -yfp expression in B. subtilis ... WebThiocillin belongs to the thiopeptide class of RiPPs due to the presence of multiple thiazoles connected to a central six-membered nitrogenous ring—in this case, a pyridine.
