In all living organisms, Coenzyme A is synthesized in a five-step process that requires four molecules of ATP, from pantothenate and cysteine: 1  Pantothenate (vitamin B5) is phosphorylated to 4'-phosphopantothenate by the enzyme pantothenate kinase (PanK; CoaA; CoaX)
Origin: From TARDIS, the time machine in British science-fiction TV programme Doctor Who. Freebase(0.00 / 0 votes)Rate this definition: The TARDIS is a time machine and spacecraft in the British science fiction television programme Doctor Who and its associated spin-offs. A TARDIS is a product of the advanced technology of the Time Lords, an extraterrestrial civilisation to which the programme's central character, the Doctor, belongs.
The Doctor is a renegade Time Lord: an eccentric, highly-intelligent scientist from a distant planet. He travels through time and space in the TARDIS, a curious device, larger on the inside than on the outside, which was designed to change its appearance to suit its surroundings. Unfortunately, the Doctor's TARDIS seems to be broken, and always appears as a blue British police box.
