Application

Application Comment Organism
medicine alpha-methylacyl-coenzyme A racemase is a biomarker for prostate cancer and a putative target for the development of therapeutic agents directed against the disease, inhibition of enzyme activity may also act synergistically with androgen ablation therapy Mycobacterium tuberculosis
