1.6.5.5	the quinone oxidoreductase activity of purified his-tagged recombinant mouse zeta-crystallin is comparable to that of purified native guinea pig lens zeta-crystallin, and to that of recombinant guinea pig zeta-crystallin. The method permits production of substantial amounts of recombinant zeta-crystallin for conducting studies on the biological role of this protein
