crystallization communications
CPIP1 from N. tabacum (NtCPIP1) is a plant heat-shock 40-type protein that participates in effector–host interactions during potyviral infections. Whereas crystals of full-length wild-type NtCPIP1 only diffracted to 8.0 Å resolution, diffraction from crystals of a shortened variant lacking the first 127 amino acids extended to 2.4 Å resolution.
