Binds to and stops, prevents or reduces the activity of metalloendopeptidases, enzymes that catalyze the hydrolysis of nonterminal peptide bonds in a polypeptide chain and contain a chelated metal ion at their active sites which is essential to their catalytic activity.

Catalysis of the reaction: citrate = cis-aconitate + H2O.

Catalysis of the posttranscriptional addition of a guanyl residue to the 5' end of a tRNA molecule; observed for His tRNAs.

Receiving vitellogenin, and delivering vitellogenin into the cell via endocytosis.

Catalysis of the reaction: H2O + coniferin = D-glucose + coniferol.

Catalysis of the reaction: a 1,2-diacylglycerol 3-phosphate + H2O = a 1,2-diacyl-sn-glycerol + phosphate.

Catalysis of the reaction: H2O + citrulline = NH3 + CO2 + L-ornithine.

Any process that stops, prevents, or reduces the frequency, rate or extent of glucokinase activity, the catalysis of the transfer of a phosphate group, usually from ATP, to a glucose molecule.

Any process that stops, prevents or reduces the frequency, rate or extent of hexokinase activity.

Any process that modulates the frequency, rate or extent of glucokinase activity, the catalysis of the transfer of a phosphate group, usually from ATP, to a glucose molecule.

Binding to a ferrous iron ion, Fe(II).

Any process that modulates the frequency, rate or extent of hexokinase activity.

OBSOLETE. (Was not defined before being made obsolete).

Binding to a ubiquitin activating enzyme, any of the E1 proteins.

Any process that activates or increases the frequency, rate or extent of glucokinase activity, the catalysis of the transfer of a phosphate group, usually from ATP, to a glucose molecule.

Any process that activates or increases the frequency, rate or extent of hexokinase activity.

Binding to a ferric iron ion, Fe(III).

Any process that modulates the frequency, rate or extent of the phosphorylation of peptidyl-serine.
