Chromatographic analysis of HutZ and two unpublished proteins A and B. Both proteins A and B exist as monomer in solution. The elution volume for A (34.7 KD) and B (17.5 KD) are 14.9 mL and 17.9 mL, respectively. The elution volume of HutZ (15 KD) was 15.7 mL. These results indicate that HutZ exists as dimer.
