Table 2. Sequence identity (%, upper triangle) and backbone r.m.s.d. values (Å, lower triangle) for cyanobacterial RbcX proteins from T. elongatus (PDB entry 3q20; this work), Synechococcus sp. PCC 7002 (2peq), Anabaena sp. CA (2peo) and Synechocystis sp. PCC 8603 (2py8).

Values were obtained with the SSM program (Krissinel & Henrick, 2004 ▶). The resolution of each crystal structure determination is specified in parentheses.
