-
the specific activities of Gal-Tr is nearly normal or slightly elevated in all the three Purkinje cell abnormality mutants
Manually annotated by BRENDA team
-
specific activities of Gal-Tr in the granule cell layer and white matter is approximately 66% of that in the molecular layer. Gal-Tr in the homogenate of cerebellum declines by approximately 35-45% from postnatal day 3 to 14. Gal-Tr activity in the granule cells does not change with age. The relative Gal-Tr activity in granule cells to homogenate is between 0.13 and 0.23
