Crystal structure of the cpSRP54 tail bound to cpSRP43

Structural highlights

3ui2 is a 2 chain structure with sequence from Arabidopsis thaliana. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:	X-ray diffraction, Resolution 3.178Å
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

SR43C_ARATH Component of the chloroplast signal recognition particle pathway. Required for post-translational targeting of proteins into the tylakoid membrane but seems to be dispensable for co-translational targeting with a translating ribosome present. May be able to function independently of cpFTSY and FFC/cpSRP54 in targeting LHCPs to the thylakoids. Acts as a highly specific chaperone for LHCPs, preventing aggregation and being able to dissolve aggregates.^[1] ^[2] ^[3] ^[4] ^[5]
