Which of the following is a characteristic of EF-hand proteins?
A)EF-hand domains usually are arranged so that 3 EF-hand domains directly contact each other.
B)EF-hand proteins dramatically change conformation upon binding Mg²⁺ ions.
C)CaM (an EF-hand protein)binds target protein with basic amphiphilic alpha helix (Baa helix)motifs.
D)Conformational changes promote dissociation of the EF-hand protein from its target protein(s).

Question

Quizplus · Accepted Answer

EF-hand proteins, such as CaM, often bind to target proteins with a basic amphiphilic alpha helix (Baa helix) motif.

Note: Options A, B, and D are not characteristics of all EF-hand proteins, as not all have three domains, change drastically upon binding Mg²⁺, or promote dissociation from their target protein.
