Proline: the distribution, frequency, positioning, and common functional roles of proline and polyproline sequences in the human proteome.
Proline is an anomalous amino acid. Its nitrogen atom is covalently locked within a ring, thus it is the only proteinogenic amino acid with a constrained phi angle. Sequences of three consecutive prolines can fold into polyproline helices, structures that join alpha helices and beta pleats as archit...
