Catalysis of the endohydrolysis of the N,N'-diacetylchitobiosyl unit in high-mannose glycopeptides and glycoproteins containing the -[Man(GlcNAc)2]Asn-structure. One N-acetyl-D-glucosamine residue remains attached to the protein; the rest of the oligosaccharide is released intact.

Catalysis of the hydrolysis of (1->4)-alpha-D-glucosidic linkages in amylaceous polysaccharides, to remove successive maltohexaose residues from the non-reducing chain ends.

Catalysis of the reaction: D-galactosyl-3-(N-acetyl-alpha-D-galactosaminyl)-L-serine + H2O = D-galactosyl-3-N-acetyl-alpha-D-galactosamine + L-serine in mucin-type glycoproteins.

Catalysis of the reaction: phosphatidylcholine + H2O = 2-acylglycerophosphocholine + a carboxylate.

Catalysis of the reaction: ATP + 4-amino-2-methyl-5-phosphomethylpyrimidine = ADP + 4-amino-2-methyl-5-diphosphomethylpyrimidine.

Catalysis of the reaction: D-ribulose 5-phosphate + ATP = D-ribulose 1,5-bisphosphate + ADP + 2 H(+).

Catalysis of the reaction: D-ribose 1-phosphate = D-ribose 5-phosphate.

Catalysis of the reaction: ATP + phosphate(n) = ADP + phosphate(n+1).

OBSOLETE. Catalysis of the preferential cleavage of Tyr16-Leu17 and Phe25-Tyr26 bonds of oxidized insulin B chain. Also acts on other substrates of Molecular weight less than 7 kDa such as insulin and glucagon.

OBSOLETE. Catalysis of the cleavage of a Gly-Phe bond to release an N-terminal, basic peptide of 5-8 residues from type IV prepilin, and then N-methylates the new N-terminal amino group, the methyl donor being S-adenosyl-L-methionine.

Catalysis of the reaction: NAD(+) + prephenate = (4-hydroxyphenyl)pyruvate + CO(2) + NADH.

Catalysis of the integration of prophage DNA into a target DNA molecule, usually a bacterial chromosome, via a sequence-specific recombination event which involves the formation of an intasome, a DNA-protein-complex designed for site-specific recombination of the phage and host DNA.

Catalysis of the endohydrolysis of 1,4-beta-D-linkages between D-galactose 4-sulfate and 3,6-anhydro-D-galactose in kappa-carrageenans.

Catalysis of the hydrolysis of pectic acid from the non-reducing end, releasing digalacturonate.

Catalysis of the hydrolysis of terminal (1->3)-alpha-D-glucosidic links in 1,3-alpha-D-glucans.

Catalysis of the hydrolysis of (1->4)-alpha-D-glucosidic linkages in amylaceous polysaccharides, to remove successive maltotetraose residues from the non-reducing chain ends.

Catalysis of the hydrolysis of (2->6)-beta-D-fructofuranan, to remove successive disaccharide residues as levanbiose, i.e. 6-(beta-D-fructofuranosyl)-D-fructose, from the end of the chain.

Catalysis of the endohydrolysis of 1,4-alpha-D-glucosidic linkages in alpha-D-glucans containing both 1,3- and 1,4-bonds.
