Calcium binding proteins all possess two or more characteristic peptide domains for Ca⁺⁺ binding that consist of a short α-helix, a loop of 12 amino acids and a second α-helix (helix-loop-helix) that is called: A) basic region leucine zipper. B) zinc finger. C) EF hand. D) beta-beta. E) none are true.

Question

Quizplus · Accepted Answer

The characteristic peptide domains for calcium binding proteins consist of an α-helix, a loop of 12 amino acids and a second α-helix, also known as the EF hand. The other options are unrelated to the peptide domains for calcium binding.
