FunFam 310: Phosphatidylcholine-sterol O-acyltransferase

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 3 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Phosphatidylcholine-sterol O-acyltransferase activity GO:0004607
Catalysis of the reaction: phosphatidylcholine + a sterol = a sterol ester + 1-acylglycerophosphocholine.
 2 Q4VCM1 (/IDA) Q4VCM1 (/IDA)
Phosphatidylethanolamine-sterol O-acyltransferase activity GO:0080095
Catalysis of the reaction: a phosphatidylethanolamine + a sterol = a sterol ester + a lysophosphatidylethanolamine.
 2 Q4VCM1 (/IDA) Q4VCM1 (/IDA)
Phosphatidate-sterol O-acyltransferase activity GO:0080096

Sterol catabolic process GO:0016127
The chemical reactions and pathways resulting in the breakdown of sterols, steroids with one or more hydroxyl groups and a hydrocarbon side-chain in the molecule.
 2 Q4VCM1 (/IMP) Q4VCM1 (/IMP)
Sterol esterification GO:0034434

 2 Q4VCM1 (/IDA) Q4VCM1 (/IDA)
Sterol esterification GO:0034434
A lipid modification process in which a sterol ester is formed by the combination of a carboxylic acid (often a fatty acid) and a sterol molecule (e.g. cholesterol).
