Abstract excerpt
All organisms require a minimal amount of metal ions to sustain their metabolism, growth and development. At the same time, their intrinsic metal-uptake systems render them vulnerable to toxic levels of metals in the biosphere. Using radiolabeled recombinant calmodulin as a probe to screen a tobacco cDNA library, we have discovered a protein designated NtCBP4 (Nicotiana tabacum calmodulin-binding protein) that...
