Enzim Rubisco adalah enzim yang ditemukan di kloroplas tumbuhan dan alga. Enzim ini berperan penting dalam fotosintesis, yaitu proses yang mengubah energi cahaya menjadi energi kimia yang tersimpan dalam bentuk glukosa.
Enzim Rubisco berfungsi untuk mengkatalisis reaksi karboksilasi, yaitu reaksi pengikatan karbondioksida (CO2) ke ribulosa bifosfat (RuBP). Reaksi ini merupakan langkah pertama dalam siklus Calvin, yang merupakan jalur utama fotosintesis.
Enzim Rubisco bekerja dengan cara mengikat CO2 dan RuBP secara bersamaan. CO2 akan terikat pada sisi aktif enzim, sedangkan RuBP akan terikat pada sisi sisi lain enzim. Setelah CO2 terikat, enzim akan melepaskan produk reaksi, yaitu 3-fosfogliserat.
Aktivitas enzim Rubisco dipengaruhi oleh beberapa faktor, antara lain:
Enzim Rubisco merupakan enzim yang sangat penting bagi kehidupan tumbuhan. Enzim ini berperan dalam fotosintesis, yang merupakan proses yang menghasilkan makanan bagi tumbuhan dan makhluk hidup lainnya.
Enzim Rubisco adalah enzim yang ditemukan di kloroplas tumbuhan dan alga. Enzim ini memiliki nama lengkap ribulose-1,5-bisfosfat karboksilase/oksigenase (Rubisco). Enzim ini merupakan enzim terbesar yang diketahui, dengan massa molekular sekitar 550 kDa.
