heat shock protein 21; T29A15.160; T29A15_160
NCBI Protein Information
heat shock protein 21
NCBI Summary
Encodes Hsp21, a chloroplast located small heat shock protein. A structure model of Hsp21, obtained by homology modeling, single-particle electron microscopy, and lysine-specific chemical crosslinking, shows that the Hsp21 subunits are arranged in two hexameric discs, rotated by 25 degree in relation to each other.
