Abstract
An iron binding protein, isolated from guinea pig intestinal mucosa, was compared to guinea pig transferrin. Both had a molecular weight of approximately 80,000. The intestinal iron-binding protein consisted of 2 subunits of equal molecular weight; transferrin had no subunits. Transferrin showed an absorbance peak at 470 nm; the intestinal iron-binding protein had no visible absorbance but did have a peak at 336 nm. Electron spin resonance spectra of the two proteins dfffered. Significant differences on amino acid analysis were also identified.
