   Fast forward a few years, and the whole family has adopted "fursonas," which they’re excited to show off at their first-ever Anthrocon. This weekend, Savannah will be a kangaroo named "Bubbles," Theresa will be a "sparkledog" named "Amethyst," Andrew will be a protogen — a computer-animal hybrid species — named "Jayden," and Carver, their son, will be a dragon named "Aiden Moonclaw."

   If you don't know what a protogen is do yourself a favor and look up some pictures of them right now—they're a really cool fusion of cute/fuzzy critter and technology!

   When it comes to furry avatars, the Protogen^([sic]) genre of avatars are by far the most popular… and with good reason too. They're slick in terms of their design, incredibly customizable, and have lots of facial features and body expressions that can be tailored for just about any player.

   It was suggested by Granick (1961) that in animal mitochondria Proto was probably formed from protoporphyrinogen (Protogen) (VIII; Fig. 1) by an enzymatic oxidation that involves the removal of six hydrogens from the Protogen ring.

   It is also said that in plants of the turnip tribe a substance occurs of the same complicated composition as the protogen of the brain, and that these elements split up naturally, in the same mauner as they do when decomposed artificially, and in both cases phosphoric acid, sugar, and nitrogenous substances like neurin and oxyneurin, result from the process.

   In each case a factor was found to be required which was not one of the known coenzymes. These factors were known variously as pyruvate oxidation factor, protogen, and thioctic acid or a-lipoic acid, but by 1952 it was evident that they were one and the same compound.

   Peroxidizing compounds inhibit the protoporphyrinogen oxidase in the bio-synthetic pathway (protox, EC 1.3.3.4) which oxidizes protoporphyrinogen (protogen; Matringe and Scalla 1988; Matringe et al. 1989). The protogen precursors uro- and coproporphyrinogen are not oxidized (Duke et al. 1994).
