title: Positive control of D-serine deaminase synthesis in vitro.
abstract: Efficient constitutive synthesis of D-serine deaminase [D-serine hydro-lyase (deaminating); EC 4.2.1.14] is obtained in vitro by using a slightly modified Zubay system programmed with dsdO6 dsdA+DNA. Synthesis from a dsdO+ dsdA+ template requires active dsdC gene product and 3':5'-cyclic AMP. In vitro synthesis of dsdC product is obtained with a dsdC+ dsdO+ dsdA+ or a dsdCc dsdO+ dsdA+ template; this synthesis is thermosensitive and can be uncoupled from D-serine deaminase synthesis by temperature shift.
