2013年10月7日 · Phospholipid:diacylglycerol acyltransferase (PDAT) and diacylglycerol:acyl CoA acyltransferase play overlapping roles in triacylglycerol (TAG) assembly in Arabidopsis, and are essential for seed and pollen development, but the functional importance of PDAT in vegetative tissues remains largely unknown.

2016年9月1日 · PDAT directly transfers an acyl group from the sn-2 position of PC to the sn-3 hydroxyl of DAG producing TAG and LPC. The re-acylation of LPC by LPCAT, would complete a PDAT based acyl editing mechanism that could channel acyl groups from the acyl-CoA pool into PC for modification, and subsequent incorporation into TAG by PDAT ( Fig. 5 ).

2005年10月7日 · Avoiding Update Cycles requires careful understanding and planning of your design. As Configurator states, you simply need to make sure that your geometry doesn't rely on each other. That's sometimes easier said than done, but …
