Miscellaneousi

Miscellaneous

Citrate synthase is found in nearly all cells capable of oxidative metabolism.
Mutation of kdn causes a behavioral mutation ('bang sensitivity' = temporarily paralysis in response to a physical jolt). Flies lacking kdn exhibit alterations in neuronal firing patterns in the giant fiber (GF) pathway.
