WebThe accumulation of PC in pah1 pah2 is suppressed by disruption of CTP:PHOSPHOCHOLINE CYTIDYLYLTRANSFERASE1 (CCT1), which encodes a key enzyme in the nucleotide pathway for PC biosynthesis. The activity of recombinant CCT1 is stimulated by lipid vesicles containing PA. WebAug 21, 2024 · CCT is the rate-limiting and regulatory enzyme in the Kennedy pathway for the synthesis of phosphatidylcholine (PC) (Figure 1 (a) ), the dominant pathway for de novo PC synthesis in nearly all eukaryotic cells [2]. Its substrates and products are water-soluble, and the CCT active site is accessible to solvent.
