Structure of ribosomal protein L1 from Methanococcus thermolithotrophicus. Functionally important structural invariants on the L1 surface

The structure of ribosomal protein L1 from M. thermolithotrophicus compared with L1 protein structures from two other sources reveals two regions which retain their structure in all three proteins. These structural invariants are involved in intermolecular interactions in the crystals and could be treated as potential RNA-binding sites.
