A PF09131 Endotoxin_mid Bacillus thuringiensis delta-Endotoxin, middle domain Domain Members of this family adopt a structure consisting of three four-stranded beta-sheets, each with a Greek key fold, with internal pseudo threefold symmetry. Thus they act as a receptor binding beta-prism, binding to insect-specific receptors of gut epithelial cells [1]. PFAM PF09131
A PF03944 Endotoxin_C delta endotoxin Domain This family contains insecticidal toxins produced by Bacillus species of bacteria. During spore formation the bacteria produce crystals of this protein. When an insect ingests these proteins they are activated by proteolytic cleavage. The N terminus is cleaved in all of the proteins and a C terminal extension is cleaved in some members. Once activated the endotoxin binds to the gut epithelium and causes cell lysis leading to death. This activated region of the delta endotoxin is composed of three structural domains. The N-terminal helical domain is involved in membrane insertion and pore formation. The second and third domains are involved in receptor binding. PFAM PF03944
A PF03945 Endotoxin_N delta endotoxin, N-terminal domain Domain This family contains insecticidal toxins produced by Bacillus species of bacteria. During spore formation the bacteria produce crystals of this protein. When an insect ingests these proteins they are activated by proteolytic cleavage. The N terminus is cleaved in all of the proteins and a C terminal extension is cleaved in some members. Once activated the endotoxin binds to the gut epithelium and causes cell lysis leading to death. This activated region of the delta endotoxin is composed of three structural domains. The N-terminal helical domain is involved in membrane insertion and pore formation. The second and third domains are involved in receptor binding. PFAM PF03945
