Proteaseassay

In certain fruits, such as pineapples and mangoes, the flesh contains protein-digesting enzymes (proteases). These may play a part in helping to soften the fruit tissues as the fruit ripens, making it even more attractive to animals that might disperse the seeds. So perhaps the activities of these proteases enzymes will increase during the ripening process.Applications of plant proteases, such as ‘bromelain’ from the......阅读全文
