To find out the regions having major influence on the
bioluminescence spectra of railroad worm luciferases, we constructed new
chimeric luciferases switching the fragments from residues 1-219 and from
220-545 between Phrixotrix viviani (PxvGR; Keywords:

Abstract
max
=548 nm) green-light emitting luciferase and Phrixothrix hirtus (PxhRE;
max = 623 nm) red light-emitting luciferases. Emission
spectrum (
max= 571 nm) and KM for luciferin in
the chimera PxRE220GR (PxhRE: 1-219; 220-545: PxvGR) suggested that
the region above residue 220 of PxvGR had a major effect on the active site.
However, switching the sequence between the residues 220-344 from PxvGR
luciferase into PxhRE (PxREGRRE) luciferase resulted in red light emission
(
max = 603 nm) indicating that the region 220-344 by itself
does not determine emission spectrum. Furthermore, the sequence before residue
220 of the green emitting luciferase is incompatible for light emission with
the sequence above residue 220 of PxhRE. These results suggest that the
fragments before and after residue 220, which correspond to distinct
subdomains, may fold differently in the green and red emitting luciferases,
affecting the active site conformation.![]()
