生物活性/药理作用

Urease activity has been shown to be inhibited by benzpyrene following exposure to light. This inhibition was due to the effect of benzpyrene on urease′s sulfhydryl groups.

样品准备说明

The enzyme is supplied as a glycerol solution. Prepare appropriate dilutions in reaction buffer. The following buffers have been shown not to inhibit urease activity: MES, HEPES, and CHES.

有效单位定义

One micromolar unit will liberate 1.0μmole of NH³ from urea per min at pH7.0 at 25°C. It is equivalent to 1.0 I.U.or 0.054 Sumner unit (1.0mg ammonia nitrogen in 5 minutes at pH7.0 at 20°C)
