Subsequent to Taylor's work, figure-of-eight knots were found in three other ketol acid reductoisomerases, as well as in several phytochromes, a transcriptional regulator, and a virus core protein (see [[http://pknot.life.nctu.edu.tw/table_new.php list at the pKnot server]]). Also, more complex knots were found, described below. | |||
