positive regulation of hydrolase activity

Any process that activates or increases the rate of hydrolase activity, the catalysis of the hydrolysis of various bonds.

Catalysis of the reaction: NADPH + H+ + 6,7-dihydropteridine = NADP+ + 5,6,7,8-tetrahydropteridine.

Catalysis of the reaction: 2-amino-4-hydroxy-6-hydroxymethyl-7,8-dihydropteridine diphosphate + 4-aminobenzoate = diphosphate + dihydropteroate.

positive regulation of transferase activity

Any process that activates or increases the rate of transferase activity, the catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from a donor compound to an acceptor.

Catalysis of the reaction: 5,6-dihydrouracil + H2O = 3-ureidopropionate.

Facilitates transport across one or more biological membranes but do not themselves participate directly in transport. These proteins always function in conjunction with one or more established transport systems. They may provide a function connected with energy coupling to transport, play a structural role in complex formation, serve a biogenic or stability function or function in regulation.

negative regulation of transferase activity

Any process that stops or reduces the rate of transferase activity, the catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from a donor compound to an acceptor.

Catalysis of the reaction: (S)-dihydroorotate + O2 = orotate + H2O2.

Any process that activates or increases the rate of lyase activity, the catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond.

Catalysis of the release of N-terminal Arg and Lys from oligopeptides when P1' is not Pro. Also acts on arylamides of Arg and Lys.

Any process that modulates the frequency, rate or extent of myoblast differentiation.

The formation from simpler components of hemoglobin, an oxygen carrying, conjugated protein containing four heme groups and globin.
