Structure of the Chloroplast Group II Intron Splicing Factor CRS2Structure of the Chloroplast Group II Intron Splicing Factor CRS2

Structural highlights

1ryn is a 1 chain structure with sequence from Zea mays. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 1.75Å
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

CRS2_MAIZE Required for the splicing of group IIB introns in chloroplasts. Forms complexes with either CAF1 or CAF2 which, in turn, interact with RNA and confer intron specificity of the splicing particles. Has no peptidyl-tRNA hydrolase activity.[1] [2] [3] [4]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
