In order to recruit new enzymes (volunteers of bdbo) and to update and digitize enzyme database, enzyme registration is going on at this link. The enzymes who registered online, were summoned on 7 January 2016 at BioTalk 6 to submit their photographs (one passport sized: 35 mm x 45 mm + one stamp sized: 20 mm x 25 mm), to receieve enzyme ID cards and get assignment for upcoming National Biology Olympiad 2016 (NBO2016). Enzymes were given the task to register student participants of NBO2016.
