DnaA-HU complex

A protein-DNA complex containing DNA-bound DnaA attached to HU. HU is a dimer encoded by two closely related genes. Essential for the initiation of replication in bacteria; stimulates the DnaA-dependent unwinding of oriC.

HU-DNA complex

A protein-DNA complex that consists of HU heterodimers (an alpha and a beta chain) assembled into octamers along DNA. HU binds to double-stranded DNA in a structure- and sequence-specific manner and bends the DNA into a nucleosome-like structure.

guanine/guanine mispair binding

Binding to a double-stranded DNA region containing a G/G mispair.

dimethylargininase activity

Catalysis of the reaction: N(G),N(G)-dimethyl-L-arginine + H2O = dimethylamine + L-citrulline.

G protein-coupled receptor kinase activity

Catalysis of the reaction: ATP + G protein-coupled receptor = ADP + G protein-coupled receptor phosphate.

G-quadruplex unwinding activity

Unwinding G-quadruplex structures in nucleic acids. A G-quadruplex is a specialized structure formed in DNA/RNA when sequences rich in guanine (G) assemble into a unique four-stranded arrangement.

heterotrimeric G-protein binding

Binding to a heterotrimeric G-protein.

G protein-coupled receptor binding

Binding to a G protein-coupled receptor.

G-protein beta-subunit binding

Binding to a G-protein beta subunit.

G-rich single-stranded DNA binding

Binding to G-rich, single-stranded DNA.
