Dimerization of a protein

The second-order rate constant for the dimerization of a protein (P)... 

Acid phosphatase is found in bee venoms as a dimer of a protein chain of about 49000 molecular weight (61, 98, 99, 100, 101, 102). Acid phosphatase activity cannot be consistently demonstrated in venoms from vespid wasps. The N-terminal sequence and the sequences of a number of proteolytic peptides from honeybee venom acid phosphatase have recently been reported (103). The venom acid phosphatase is more closely related to mammalian prostatic type acid phosphatases (104, 105, 106, 107, 108) than to lysosomal type acid phosphatases (109, 110), as is illustrated in Fig. 5.
