===Pseudomonas aeruginosa E2Q/H83Q/M109H-azurin RE(PHEN)(CO)3===

~~==Overview==~~

<!--

The ~~triplet metal-to-ligand charge transfer ((3)MLCT) dynamics of two structurally characterized Re(I)(CO)(3)(phen)(HisX)-modified (phen = 1~~,~~10-phenanthroline; X = 83~~, ~~109) Pseudomonas aeruginosa azurins have been investigated by picosecond time-resolved infrared (TRIR) spectroscopy in aqueous (D(2)O) solution. The (3)MLCT relaxation dynamics exhibited by~~ the ~~two Re(I)-azurins are very different from those of~~ the ~~sensitizer [Re~~(~~I)(CO)(3)(phen)(im)](+) (im = imidazole)~~. ~~Whereas the Re(I)(CO)(3) intramolecular vibrational relaxation in Re(I)(CO)(3)(phen)(HisX)Az (4 ps~~) is ~~similar to that of [Re(I)(CO)(3)(phen)(im)](+) (2 ps),~~ the ~~medium relaxation is much slower ( approximately 250 vs 9~~.~~5 ps); the 250~~-~~ps relaxation is attributable to reorientation of D(2)O molecules as well as structural reorganization of the rhenium chromophore and nearby polar amino acids in each of the modified proteins.~~
