Analysis of EF-hand-containing proteins in

Three out of the four classes of Ca2+-binding proteins in plants contain Ca 2+ -binding EF-hand motif(s). A maximum of 250 proteins possibly having EF-hands were identified. Diverse proteins, including enzymes, proteins involved in transcription and translation, protein- and nucleic-acid-binding proteins and a large number of unknown proteins, have one or more putative EF-hands.
