Dear Atul, Whilst finding Se-Met conditions you could always just phase with mercury if you are lucky enough to have an accessible free Cys residue or try NaI or I3C soaks. Always worth trying if you have readily reproducible crystals… Best of luck Marc From: atul kumar mailto:atulsingh21...

Don't forget to do seeding with the native crystals: it's often more about nucleation than growth. Phx Sent from tiny silly touch screen - Reply message - From: "Frederic VELLIEUX" Date: Mon, Jun 13, 2011 07:37 Subject: [ccp4bb] Fwd: Regarding Sel-Met containing proteing crystallisatio

I've had exactly the same with an enzyme from Trypanosoma brucei, native enzyme gives ca. 2 A data, a search around the crystallization conditions for the Se-Met enzyme returns absolutely nothing. What I should do is to search for new crystallisation conditions (which I won't do: trypanosome me
