dimethylargininase activity

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

mRNA (2'-O-methyladenosine-N6-)-methyltransferase activity

Catalysis of the reaction: S-adenosyl-L-methionine + m(7)G(5')pppAm = S-adenosyl-L-homocysteine + m(7)G(5')pppm(6)Am.

isopenicillin-N N-acyltransferase activity

Catalysis of the reaction: phenylacetyl-CoA + isopenicillin N + H2O = CoA + penicillin G + L-2-aminoadipate.

group III metabotropic glutamate receptor activity

A G protein-coupled receptor that is activated by L-AP-4 and inhibits adenylate cyclase activity.

protein-arginine omega-N monomethyltransferase activity

Catalysis of the addition of a methyl group to either of the unmethylated terminal nitrogen atoms (also called omega nitrogen) in peptidyl-arginine to form an omega-N-G-monomethylated arginine residue. The reaction is S-adenosyl-L-methionine + [protein]-L-arginine = S-adenosyl-L-homocysteine + [protein]-Nomega-methyl-L-arginine.

mRNA 5'-cap (guanine-N7-)-methyltransferase activity

Catalysis of the reaction: S-adenosyl-L-methionine + G(5')pppR-RNA = S-adenosyl-L-homocysteine + m7G(5')pppR-RNA. m7G(5')pppR-RNA is mRNA containing an N7-methylguanine cap; R may be guanosine or adenosine.

tubulin-tyrosine carboxypeptidase

Catalysis of the reaction: C-terminal L-alpha-aminoacyl-L-glutamyl-L-glutamyl-L-tyrosyl-[tubulin] + H2O = C-terminal L-alpha-aminoacyl-L-glutamyl-L-glutamyl-[tubulin] + L-tyrosine.

protein-glutamic acid ligase activity, elongating

Catalytic reaction :(L-glutamyl)n-L-gamma-glutamyl-L-glutamyl-[protein] + ATP + L-glutamate = (L-glutamyl)n+1-L-gamma-glutamyl-L-glutamyl-[protein] + ADP + H+ + phosphate.

cyanophycin synthetase activity (L-arginine-adding)

Catalysis of the reaction: ATP + [L-Asp(4-L-Arg)]n-L-Asp + L-arginine = ADP + phosphate + [L-Asp(4-L-Arg)]n+1.

cyanophycin synthetase activity (L-aspartate-adding)

Catalysis of the reaction: ATP + [L-Asp(4-L-Arg)]n + L-Asp = ADP + phosphate + [L-Asp(4-L-Arg)]n-L-Asp.
