Abstract
Mutation of a novel cry-like gene (cry256) from Bacillus thuringiensis resulted in a protein crystal, normally located within the spore's exosporium, being found predominately outside the exosporium. The cry256 gene codes for a 3-domain Cry-like protein that does not correspond to any of the known Cry protein holotypes.
摘要
新型 cry 样基因（cry256）的突变导致原本位于芽孢外孢囊内的蛋白晶体主要出现在外孢囊外。cry256 基因编码一个具有 3 个结构域的 Cry 样蛋白，与任何已知的 Cry 蛋白原型都不对应。
