Dear colleges!
What advantage gives Inteins for cell or organisms? Why protein splicing present in all three branches of life. Any one has ideas about this phenomenon?

Thank for link, but I interesting of biological function of intein. Do you now something about this?

I think that at least, it's the only way to keep the two proteins in a ratio of 1:1.

Not a all. For today I find several other functions or possible functions of inteins - catalitic, variability and maturation providing, etc. If you will be interested for these, please feel free to e-mail me.
