HutB, the periplasmic hemin binding protein of Photobacterium damselae subsp. piscicida, was produced as a recombinant protein. UV-Vis spectrophotometrical analysis showed absorption spectral changes in hemin upon mixing it with the recombinant protein, indicating complex formation. Spectrophotometric titration of HutB with hemin showed saturation at a heme/HutB ratio of 1:1 and a binding affinity (K4) of 10μM.

Abstract
HutB, the periplasmic hemin binding protein of Photobacterium damselae subsp. piscicida, was produced as a recombinant protein. UV-Vis spectrophotometrical analysis showed absorption spectral changes in hemin upon mixing it with the recombinant protein, indicating complex formation. Spectrophotometric titration of HutB with hemin showed saturation at a heme/HutB ratio of 1:1 and a binding affinity (K4) of 10μM.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
