[ccp4bb] molecular replacement in phaser

2009-11-10 Thread Lisa Wang
Hi all, I got one data about 3.0 A, belong to C2 space group. There are two protein molecules and one 18-nt dsRNA per ASU. The structure of last 100aa (C-terminal) has been reported, and 400 aa at N-terminalhe has homology structure with sequence identiy 30%. I try to solve it by MR with phaser.
