Let's look what alignment variants we actually have at this puzzle. It's easy to see there is only one place where we can play with alignment sequence: at the place of 2-aa size space. Changing at any other places will cause huge alignment points reduce. Known protein has the following aa sequence at that place:
And our protein has at start:
So, now we can place two spaces within this six positions as we wish: they all will give 121 alignment points. I've tryed almost all of the variants. There is table of points for some of them (after alignment and the same sequence of recipes, which I found good):
The last one is the best I think, so I've played with it some more time, and now I have 9293 points. If you can to proof any other alignment variant is better, post it here, please.
