Re: Paramutation

... exceptions from paramutation rule. So two genes are involved? This reminds me on prions,as prion protein originates from normal protein but it's conformation changed(often higher percent of beta sheets..).

Re: endorphins

... of intact versus digested CBE (this is called difference spectroscopy). This suggests the molecule in solution has a stable three-dimensional conformation, because its UV spectrum differs from that of the free amino acids. By comparing the difference spectra with time-release of peptides, ...

enzyme question

1- Yes of course. 2- just as any other inorganic catalyst work, they just cause changes in the chemical conformation of the substrate that wil make a reaction more likely.

Re: How many H+ are necessary to drive the synthesis on ONE ATP?

Hi, The current evidence suggests 3 H+ are require to synthesise 1 ATP molecule. One H+ moves the ATP sythase one conformation between open, loose, tight etc. So therefore 3 H+ are requireed for one full cyle and thus production of 1 ATP. Hope this makes sense, Harvey :wink:
