{"product_id":"nsj-v4372-20ug","title":"GCHFR Antibody \/ GFRP, 20 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":"20 ug","offer_id":48534766387424,"sku":"V4372-20UG","price":259.0,"currency_code":"KRW","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0601\/9330\/8896\/files\/get_image_06a6e5ba-7874-41e6-9dae-a94e1f5c752c.jpg?v=1768284242","url":"https:\/\/rndmate.com\/products\/nsj-v4372-20ug","provider":"알앤디메이트","version":"1.0","type":"link"}
