HEPES 0-5 ferritin heavy chain 1 Homo sapiens 28-39 11595385-7 2001 The kinetic parameters for the reaction of recombinant human H apoferritin with Fe(II) in HEPES buffer (100 mM) were: K(m) = 60 microM, k(cat) = 10 s(-1), and k(cat)/K(m) = 1.7 x 10(5) M(-1) x (-1). HEPES 90-95 ferritin heavy chain 1 Homo sapiens 63-74
