WebJul 5, 2012 · Chitin synthase is an integral membrane protein, which resides in plasma membranes and in the membranes of specialized trans-Golgi vesicles called chitosomes ( Bracker et al., 1976 ). These vesicles seem to act as an endosomal reservoir for particular isoforms of the enzyme in fungi ( Bartnicki-Garcia, 2006 ). WebChitin Synthase is manufactured in the rough endoplasmic reticulumof fungi as the inactive form, zymogen. The zymogen is then packaged into chitosomes in the golgi apparatus. Chitosomes bring the zymogen to the hyphaltip of a mold or yeast cell membrane.
