How hard would it be to determine Rubisco's mechanism directly?

[PhiJ]

I have been learning about the calvin cycle, and have been told that people think that ribulose bisphosphate is first converted into a 6 carbon sugar as a very short life intermediate, and then is converted to phosphoglyceric acid.
Why can't you just synthesise rubisco, work out its structure and mechanism of action etc. and then find if that is true. I'm sure its a lot harder than I'm thinking of it being, but how much?

have you tried google?

I hadn't. Now I have though, I know that they have sequenced it, but still don't know about the intermediate, surely it would be easy to find... why is it so hard?

define: Calvin Cycle

I've tried it. Couldn't see anything about the 6 carbon intermediate though.
