APAKAH MAKSUD COOPERATIVITY dalam CORSICA?
Kerjasama
Kerjasama adalah fenomena yang ditunjukkan oleh sistem yang melibatkan unsur-unsur yang serupa atau hampir serupa, yang bertindak secara tidak bebas antara satu sama lain, berbanding sistem hipotetikal yang tidak berinteraksi di mana unsur-unsur individu bertindak secara bebas. Satu manifestasi ini adalah enzim atau reseptor yang mempunyai banyak tapak yang mengikat di mana pertalian tapak mengikat untuk ligan nampaknya meningkat, koperasi positif, atau berkurangan, koperasi negatif, apabila mengikat ligan ke tapak yang mengikat. Sebagai contoh, pertalian empat hemoglobin untuk mengikat oksigen meningkat di atas hemoglobin yang tidak terkawal apabila molekul oksigen pertama mengikat. Ini dirujuk sebagai mengikat koperasi. Kami juga melihat kerjasama dalam molekul rantaian besar yang terbuat dari banyak subunit yang sama, apabila molekul tersebut menjalani peralihan fasa seperti lebur, terungkap atau berehat. Ini disebut sebagai koperasi subunit. Walau bagaimanapun, definisi koperasi berdasarkan kenaikan atau penurunan yang jelas dalam pertalian kepada langkah-langkah pengikatan ligan yang berturut-turut adalah bermasalah, kerana konsep "tenaga" mesti sentiasa ditakrifkan berhubung dengan keadaan piawai.
Definisi cooperativity dalam kamus Corsica
Takrif koperasi dalam kamus adalah interaksi antara unit struktur dalam molekul atau antara molekul dalam kumpulan yang membolehkan sistem bertindak balas dengan lebih mendadak kepada perubahan luaran daripada unit terpencil.

ence between the real Ka of A-B and this estimated value is considered the
cooperativity. However, using AG° = -RTlnX and Eq. 4.22 leads to Eq. 4.23. This
gives an empirical way to measure the cooperativity. One experimentally

Enzyme Catalysis and Regulation
This is in agreement with Eq. (8-7); moreover, since KaKb/(K, + K) < (K, + K1,),
this isotherm has the same form as if negative cooperativity is occurring. For
identical sites, with negative or positive cooperativity, K, = K, and K, = K, so that ...

Thermodynamics in Biology
A large body of experimental data suggests that biological macromole- cules
accomplish diverse functions using cooperative interactions among structural
domains. The best-known example of cooperativity is offered by hemoglobin, in
which ...

Progress in Drug Research
The interactions could be either attractive or repulsive leading to positive or
negative cooperativity, respectively. More complex models, such as the histone-
DNA complex in the nu- cleosome [14], can be constructed along these same
lines.

If the binding at one site increases the likelihood of binding at the next site, a
positive cooperativity exists. If in contrast the affinity for the subsequent binding
event falls, a negative cooperativity exists. This phenomenon is called allostery
and ...
