Electrophoresis and gel-filtration revealed that the active enzyme is a monomer with molecular weight of 46-47 kD. The enzyme possessed phosphomonoesterase and phosphodiesterase activities with maximal levels at pH 9.5 and 55 degreesC and was stable until 60 degreesC at pH 8.0-10.0. The isolated APase exhibits a broad specificity towards a wide variety of substrates. The effect of divalent metal ions and other reagents on its catalytic activities was studied. It was concluded that alkaline phosphatase of B. intermedius is similar to the secreted alkaline phosphatases from other Bacillus species in its physicochemical and catalytic properties.","tracks":[{"project":"bionlp-st-bb3-2016-training","denotations":[{"id":"T1","span":{"begin":0,"end":89},"obj":"Title"},{"id":"T2","span":{"begin":90,"end":956},"obj":"Paragraph"},{"id":"T3","span":{"begin":68,"end":88},"obj":"Bacteria"},{"id":"T4","span":{"begin":196,"end":222},"obj":"Bacteria"},{"id":"T5","span":{"begin":816,"end":830},"obj":"Bacteria"},{"id":"T6","span":{"begin":891,"end":899},"obj":"Bacteria"}],"attributes":[{"subj":"T1","pred":"source","obj":"bionlp-st-bb3-2016-training"},{"subj":"T2","pred":"source","obj":"bionlp-st-bb3-2016-training"},{"subj":"T3","pred":"source","obj":"bionlp-st-bb3-2016-training"},{"subj":"T4","pred":"source","obj":"bionlp-st-bb3-2016-training"},{"subj":"T5","pred":"source","obj":"bionlp-st-bb3-2016-training"},{"subj":"T6","pred":"source","obj":"bionlp-st-bb3-2016-training"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"bionlp-st-bb3-2016-training","color":"#ecdb93","default":true}]}]}}
