Spore cortex and coat synthesis

Web26 Sep 2014 · Spore coat structure and assembly have been best studied in the model spore former Bacillus subtilis and ∼70 spore specific proteins have been identified in the spore coat , , , . In addition, a number of these coat proteins undergo covalent modifications including proteolytic cleavage, cross-linking, and tyrosine peroxidation. WebSpore-coat proteins are found in a multilayered proteinaceous structure encasing the spore core and the cortex. They are involved in coat assembly, cortex synthesis and germination.
