Evidence for the presence of quinone methide isomerase in the metacercarial cyst of Microphallus sp. (Trematoda: Microphallidae)

, : Evidence for the presence of quinone methide isomerase in the metacercarial cyst of Microphallus sp. (Trematoda: Microphallidae). Parasitology 103 Pt 2: 299-303

The white colour of the cyst wall of the metacercaria of Microphallus sp, even in the presence of dihydroxy phenol and phenoloxidase, is due to proteins generated through a possible quinone methide interaction. The quinone methide isomerase converts the phenoloxidase mediated quinone into .beta.-hydroxy catechol. Formation of catechol from quinone by cyst extracts was observed spectrophotometricallty and chromatographically. This enzyme is involved in detoxification of excess quinone and .beta.-sclerotization of the cyst wall.
