Figure 1. Cartoon model of donor-only labeled apoflavodoxin (i.e., flavodoxin without FMN).

Figure 1

A488 is shown in bright green and is attached to residue 69. Flavodoxin’s three tryptophan residues (i.e., Trp74, Trp128 and Trp167) are shown in orange. The model in B is rotated by 180 degrees along the z-axis, compared to the model shown in A. Cartoon models are generated with PyMOL (Schrödinger, LLC, Palo Alto, Ca, USA) using the crystal structure of A. vinelandii flavodoxin (pdb ID 1YOB [41]) and the molecular structure of A488, as provided by Invitrogen. Apoflavodoxin strongly resembles flavodoxin, except for dynamic disorder in the flavin-binding region.
