ASES is 59% identical to Artemisia cyclase cDNA clone cASC125, 50% identical to epi-cedrol synthase from A. annua, 48% identical to amorpha-4, 11-diene synthase from A. Annua, 39% identical to the 5-epi-aristolechene synthase from tabacco, 38% identical to vetispiradiene synthase from H. Muticus, 41% identical to the δ-cadinene synthase from cotton. The coding region of cDNA was cloned into procaryotic expression vector pET30a and overexpressed in E. coli BL21 (DE3). The cyclase proteins extracted from bacterial culture were found largely in the insoluble protein fraction. The tissue specific expression patterns were analyzed by RT/PCR.
