[E]very yeast cell churns out about 1.26 million individual PMA1 molecules, making it the second-most abundant cellular protein.

Which, of course, leaves me wondering what the *first*-most abundant cellular protein might be, and ready to smack the writer of the article for keeping us hanging like that.

A piece of the larger Ribosome?

I noticed that the article didn't discuss the role of regulatory genes in preventing changes to PMA1. Seems like they might've made a mention of it.

I'm reading James Valentine's book, "On the Origin of Phyla". He spends a lot of time talking about regulatory genes controlling gene change as the molecular basis for evolution.

Again I remind everyone that I'm a physicist, not a biologist.
