Alignment of soybean NF-YC domains. The referred sequences are from Arabidopsis (At), Medicago (Mt), human (Hs), mouse (Rn) and yeast (Sc). Numbers in parentheses are the actual amino acid numbers of the start and end of domain NF-YC. Required amino acids (Required AA) are important for DNA binding and subunit interaction from yeast (Xing et al. 1993) and rat (Maity and de Crombrugghe 1992). The putative H-bonds between arginine (R) and aspartate (D) were indicated in the bottom line. NC2α and Dpb (or DRAP1) groups which are homologous to NF-YC are included
