The Phaeodactylum tricornutum (P. tricornutum) thioesterase PtTE was encoded by a 648 bp open reading frame. The deduced 216 amino acids showed no similarity with plant acyl-acyl carrier protein (ACP) thioesterases and bacterial thioesterases. Southern blot analysis revealed that one copy of PtTE was present in the P. tricornutum genome, and Real-time quantitative PCR showed that PtTE was up-regulated upon nitrogen deprivation. Thioesterase activity of PtTE was established by heterologous… CONTINUE READING
