Abstract
Appearance of uricase activity in radicles in the early stage of seed germination of soybean, non-nodulating variety A62–2, was coincident with the increase in contents of uricase cofactor. With aging, the radicles lost uricase activity without a decrease of uricase apoprotein, indicating the decrease of uricase cofactor. The uricase cofactor could be produced in aerobic conditions. The uricase cofactor was degraded by a protein having maximum activity at pH 6.5. The protein participating in the cofactor degradation could not be detected in 1 or 2-day-old seedlings, but was detected in the later stage. Uricase apoprotein was present in all the developmental stages of soybean root in spite of the absence of uricase activity. When the mature stem of a soybean plant, non-nodulating variety, was decapitated, uricase activity was elicited in the roots in accordance with the increase in the level of the uricase cofactor.
