1. A composition comprising a circularly permuted polypeptide having an N-terminal segment linked to a C-terminal segment, wherein the N-terminal segment of the circularly permuted polypeptide has at least 95% sequence identity to a portion of SEQ ID NO: 89 from a circular permutation site to the C-terminus of SEQ ID NO: 89, wherein the C-terminal segment of the circularly permuted polypeptide has at least 95% sequence identity to a portion of SEQ ID NO: 89 from the N-terminus to the circular permutation site of SEQ ID NO: 89, wherein the circular permutation site is within a transition between predicted protein structural motifs of a polypeptide of SEQ ID NO: 89, and wherein the circularly permuted polypeptide exhibits luciferase activity in the presence of a coelenterazine substrate.
