Spectroscopic properties of Anabaena sp. strain PCC7120 holo-HT-PecA expressed in E. coli. Shown are the absorbance (λmax, 561 nm) (thick solid line), control Anabaena sp. strain PCC7120 holo-PecA (from the study of Bryant et al. [5]) (thin solid line), and fluorescence emission ( 
, 582 nm; λexc, 550 nm) (dashed line) spectra for HT-PecA purified from E. coli by affinity chromatography. The spectra were normalized at 561 nm to the absorbance spectrum of holo-PecA from E. coli.
