'''BROMOPEROXIDASE A2'''<br />


==Overview==
==BROMOPEROXIDASE A2==
The crystal structure of the bromoperoxidase A2 from Streptomyces, aureofaciens (ATCC 10762) has been determined by isomorphous replacement, and refined to 2.05 A resolution with an R-value of 18.4%. The enzyme, catalyzes the bromination of organic compounds in the presence of bromide, and peroxide. The structure confirms the absence of cofactors such as, metal ions or haem groups and shows the general topology of the alpha/beta, hydrolase fold. The active centre is at the end of a deep pocket and, includes a catalytic triad of Ser 98, Asp 228 and His 257. The active, centre is connected by a narrow tunnel to a second pocket on the enzyme, surface.
