    Construction of a Bacillus thuringiensis genetically-engineered strain harbouring the secreted Cry1Ia delta-endotoxin in its crystal 

    Dammak, Mariam; Jaoua, Samir; Tounsi, Slim ( Springer Netherlands , 2011 , Article)
    Unlike other Bacillus thuringiensis Cry proteins, Cry1 Ia does not form a crystal since it is a secreted delta-endotoxin. We have engineered a Cry1 Iac chimeric protein by substituting the C-terminal part of Cry1 Ia by the ...
