Abstract
Escherichia coli RNA polymerase exists in two different forms, one less active than the other under standard assay conditions. Conversion of the active to the inactive form requires ATP-Mg(++). The reverse, inactive to active enzyme conversion, requires Mg(++). Covalently bound adenylic acid residue(s) are contained in the inactive form.
摘要
大肠杆菌RNA聚合酶以两种不同形式存在，在标准测定条件下，其中一种形式的活性低于另一种。活性形式向非活性形式的转变需要ATP-Mg(++)。相反，非活性形式向活性酶形式的转变需要Mg(++)。非活性形式含有共价结合的腺苷酸残基。
