{"product_id":"v4372-20ug","title":"GCHFR Antibody \/ GFRP","description":"\u003cp\u003eGTP cyclohydrolase I feedback regulatory protein (GFRP) is encoded by the gene GCHFR. GFRP mediates feedback inhibition of GTP cyclohydrolase I activity by tetrahydrobiopterin. GFRP also acts as a mediator for the stimulatory effect of phenylalanine on enzyme activity. L-phenylalanine reverses this inhibition. Cross-linking experiments have shown that GFRP is usually expressed as a homodimer or pentamer.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"20 ug \/ Mouse","offer_id":46764651610336,"sku":"V4372-20UG","price":249.0,"currency_code":"KRW","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0601\/9330\/8896\/files\/get_image_9683a2f1-4352-4ccc-acc4-c751e02830ae.jpg?v=1734424019","url":"https:\/\/rndmate.com\/products\/v4372-20ug","provider":"알앤디메이트","version":"1.0","type":"link"}
