AbstractThousands of organohalogen compounds have been found in marine and terrestrial organisms (Gribble, 1999). Many of these halogenated natural products have biological activities, such as antibacterial, antifungal, antiviral, and anti-inflammatory activities (Butler and Carter-Franklin, 2004). These enzymes were divided into three groups: haloperoxidases, perhydrolases, and FADH2-dependent halogenases (van Pée and Zehner, 2003). Marine sponges as the rich resource of marine natural product, including many halogenated metabolites (Nickel et al., 2001), however, are rarely reported for their halogenase activities. This study aimed to investigate the haloperoxidase activities from fivemarine sponges of Craniella australiensis, Reniochalina sp., Axinella sp., Hymeniacidon perlevis and one unidentified sponge collected from China Seas, in order to understand the distribution, role and origin of the sponge-derived halogenases. Axinella sp. and Reniochalina sp. showed bromoperoxidase activity of 9.5 U/g wet sponge and 10.6 U/g wet sponge, respectively. All five marine sponges showed iodoperoxidase and peroxidase activity, but did not exhibit chloroperoxidase activity. Preliminary purification and characterization of the haloperoxidase from Axinella sp. has been carried out to give the optimum pH at 6.0 and isoelectric point bellow physiological pH. The haloperoxidase from Axinella sp. was unstable.
