Metaloprotein

Metaloprotein ialah sebuah istilah bagi protein dengan kofaktor ion logam.^[1]^[2] Banyakprotein yang diketahui tergolonng dalam kumpulan ini. Sebagai contoh, sekurang-kurangnya 1000 protein manusia (daripada sekitar 20,000) domain protein dengan ikatan atom zink^[3] walaupun diduga mungkin ada sehingga 3000 metaloprotein zink dalam manusia.^[4]

Limpahan

Anggaran menduga bahaw kira-kira separuh daripada semua protein yang wujud memiliki logam.^[5] Dalam satu lagi anggaran, sekitar suku hingga sepertiga protein yang wujud memerlukan logam untuk menjalankan fungsinya.^[6] Oleh itu, metaloprotein memiliki banyak fungsi dalam sel seperti penyimpanan dan pengangkutan protein.^[7] Limpahan metaloprotein ini mungkin telah diwarisi daripada asid amino yang membentuk protein memandangkan protein buatan juga ditemui bersedia berikat dengan atom-atom logam.^[8]
