{"product_id":"v4384saf-100ug","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":"100 ug \/ Mouse","offer_id":46764644401376,"sku":"V4384SAF-100UG","price":539.0,"currency_code":"KRW","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0601\/9330\/8896\/files\/get_image_b34bdc50-0889-412d-b308-1a8fdea8a8db.jpg?v=1734423907","url":"https:\/\/rndmate.com\/products\/v4384saf-100ug","provider":"알앤디메이트","version":"1.0","type":"link"}
