{"product_id":"nsj-v4384-100ug","title":"GFRP Antibody \/ GCHFR, 100 ug","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":"100 ug","offer_id":48534764454112,"sku":"V4384-100UG","price":559.0,"currency_code":"KRW","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0601\/9330\/8896\/files\/get_image_63debf9c-3260-467e-a189-4d76f744edc4.jpg?v=1768284202","url":"https:\/\/rndmate.com\/products\/nsj-v4384-100ug","provider":"알앤디메이트","version":"1.0","type":"link"}
