APAKAH MAKSUD PECTINESTERASE dalam CORSICA?
Pectinesterase
Pektinesterase adalah enzim yang berkaitan dengan dinding sel yang membentangkan beberapa isoform yang memudahkan pengubahsuaian dinding sel tumbuhan dan kerosakan berikutnya. Ia dijumpai di semua tumbuhan yang lebih tinggi serta dalam beberapa bakteria dan kulat. Fungsi pectinesterase terutamanya dengan mengubah pH setempat dinding sel yang mengakibatkan perubahan dalam integriti dinding sel. Pektinesterase memangkinkan de-esterifikasi pektin menjadi pektat dan metanol. Pektin adalah salah satu komponen utama dinding sel tumbuhan. Dalam tumbuh-tumbuhan, pektinesterase memainkan peranan penting dalam metabolisme dinding sel semasa buah masak. Dalam patogen bakteria tumbuhan seperti Erwinia carotovora dan patogen jamur seperti Aspergillus niger, pektinesterase terlibat dalam pemusnahan dan pembekuan lembut tisu tumbuhan. Pektinesterase tumbuhan dikawal oleh pektinesterase inhibitor, yang tidak berkesan terhadap enzim mikrob.
