Gene

ECT1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Ethanolamine-phosphate cytidylyltransferase which catalyzes the second step of phosphatidylethanolamine biosynthesis. Involved in the maintenance of plasma membrane and required for proper sporulation.2 Publications

Catalytic activityi

CTP + ethanolamine phosphate = diphosphate + CDP-ethanolamine.

Pathwayi: phosphatidylethanolamine biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes phosphatidylethanolamine from ethanolamine.
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. Ethanolamine kinase (EKI1)
  2. Ethanolamine-phosphate cytidylyltransferase (ECT1)
  3. Choline/ethanolaminephosphotransferase 1 (EPT1)
This subpathway is part of the pathway phosphatidylethanolamine biosynthesis, which is itself part of Phospholipid metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes phosphatidylethanolamine from ethanolamine, the pathway phosphatidylethanolamine biosynthesis and in Phospholipid metabolism.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
