Acetyl-coenzyme A(CoA) synthetase(ACS) catalyzes the synthesis of acetyl-CoA and is one of the important hubs of fat and acetate metabolism. In this study, reverse-transcription polymerase chain reaction(RT-PCR) and rapid amplification of c DNA ends(RACE) techniques were used to obtain ACS c DNA from Dunaliella tertiolecta(Dt ACS). The c DNA contained 2,464 base pairs(bp)(full-length). The predicted length of open reading frame(ORF) was 2,184 bp, and 727 amino acids were encoded by the ORF. Sequence alignme...
