Comparison of the amino acid sequences of HRGP330 with active (HRGP335) and inactive (HRGP365 and HRGP398) peptides derived from the proteolytic fragment of HRG33. All His residues present in the active HRGP335 are conserved in the inactive HRGP365, which contains two additional His residues in the equivalent region. The His/Cys/Pro-rich peptide HRGP398 was also inactive.
