Other claims from this paper (4)
- Observation The evolutionary pathway of single-domain germins was traced back.
- Observation Germins and oxalate decarboxylases were inferred to share evolutionary roots in bacterial and archaebacterial cupin-module proteins.
- Observation The inferred root proteins may reflect a pro-cupin ancestral to some cupin superfamily members.
- Observation A beta-barrel in otherwise unrelated archaeal and bacterial epimerases exemplifies structural convergence.
