1CT8 - PubMed Abstract: 
Small organic molecules coupled to a carrier protein elicit an antibody response on immunisation. The diversity of this response has been found to be very narrow in several cases. Some antibodies also catalyse chemical reactions. Such catalytic antibodies are usually identified among those that bind tightly to an analogue of the transition state (TSA) of the relevant reaction; therefore, catalytic antibodies are also thought to have restricted diversity. To further characterise this diversity, we investigated the structure and biochemistry of the catalytic antibody 7C8, one of the most efficient of those which enhance the hydrolysis of chloramphenicol esters, and compared it to the other catalytic antibodies elicited in the same immunisation.
