| Abstract: | Mangrove sediments exhibited higher activity of -glutaminase (-glutamine aminohydrolase, EC 3.5, 1.2) compared to sediments collected from other biotopes. Clayey sediments showed higher enzyme activity than the silty ones. The enzyme showed 2 pH optima (at 5.6 and 8.4) but maximum activity was observed at pH 8.4. KM of -glutaminase was 1 x 10-4 M and activity of the enzyme was unaffected by sodium chloride even up to a 10% conc. Citrate ions inhibited the enzyme activity. Glutaminase activity was comparatively higher than asparaginase in all sediment samples collected from different biotopes. |
