产品介绍
酪氨酸酶( Tyrosinase) 又称酚氧化酶、多酚氧化酶、儿茶酚氧化酶,是结构复杂的多亚基的含铜氧化还原酶,广泛存在于微生物、动植物及人体中。
酪氨酸酶具有独特的双重催化功能,是生物体内黑色素合成的关键酶,与人的衰老,昆虫的伤口愈合与发育,果蔬的褐变有密切关系。多年来,酪氨酸酶一直受到国内外的关注,其研究涉及生物、医学、农学、化学、药学等多个学科和领域.酪氨酸酶作为黑色素合成的关键酶,其异常过量表达可导致人体的色素沉着性疾病。
背景资料
This is a copper-containing oxidase that functions in the formation of pigments such as melanins and other polyphenolic compounds. Catalyzes the initial and rate limiting step in the cascade of reactions leading to melanin production from tyrosine. In addition to hydroxylating tyrosine to DOPA (3,4-dihydroxyphenylalanine), also catalyzes the oxidation of DOPA to DOPA-quinone, and possibly the oxidation of DHI (5,6-dihydroxyindole) to indole-5,6 quinone.
亚细胞定位
Melanosome membrane; Single-pass type I membrane protein.
疾病
Defects in TYR are the cause of albinism oculocutaneous type 1A (OCA1A) [MIM:203100]; also known as tyrosinase negative oculocutaneous albinism. An autosomal recessive disorder in which the biosynthesis of melanin pigment is absent in skin, hair, and eyes. It is characterized by complete lack of tyrosinase activity due to production of an inactive enzyme. Patients present with a life-long absence of melanin pigment after birth, and manifest increased sensitivity to ultraviolet radiation with predisposition to skin cancer. Visual anomalies include decreased acuity, nystagmus, strabismus and photophobia.
Defects in TYR are the cause of albinism oculocutaneous type 1B (OCA1B) [MIM:606952]; also known as albinism yellow mutant type. An autosomal recessive disorder in which the biosynthesis of melanin pigment is reduced in skin, hair, and eyes. It is characterized by partial lack of tyrosinase activity. Patients have white hair at birth that rapidly turns yellow or blond. They manifest the development of minimal-to-moderate amounts of cutaneous and ocular pigment. Some patients may have with white hair in the warmer areas (scalp and axilla) and progressively darker hair in the cooler areas (extremities). This variant phenotype is due to a loss of tyrosinase activity above 35-37 degrees C.
