FunFam 700: ATP-dependent DNA helicase DinG

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 5 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
DNA helicase activity GO:0003678
Catalysis of the reaction: ATP + H2O = ADP + phosphate; this reaction drives the unwinding of the DNA helix.

DNA/RNA helicase activity GO:0033677
Catalysis of the reaction: ATP + H2O = ADP + phosphate; this reaction drives the unwinding of a DNA/RNA duplex, i.e. a double helix in which a strand of DNA pairs with a complementary strand of RNA.

4 iron, 4 sulfur cluster binding GO:0051539
Interacting selectively and non-covalently with a 4 iron, 4 sulfur (4Fe-4S) cluster; this cluster consists of four iron atoms, with the inorganic sulfur atoms found between the irons and acting as bridging ligands.
