In molecular biology, binding domain is a protein domain which binds to a specific atom or molecule, such as calcium or DNA. A protein domain is a part of a protein sequence and a tertiary structure that can change or evolve, function, and live by itself independent of the rest of the protein chain.[1] Upon binding, proteins may undergo a conformational change. Binding domains are essential for the function of many proteins. They are essential because they help splice, assemble, and translate proteins.[2]
Examples of binding domains include the Zinc finger, which binds to DNA, and EF hand, which binds to calcium.[citation needed]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
