Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of deprivation of sulfate.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of deprivation of nourishment.

Any process involved in the maintenance of an internal steady state of magnesium ions within an organism or cell.

Any process involved in the maintenance of an internal steady state of divalent cations within an organism or cell.

Any process involved in the maintenance of an internal steady state of metal ions within an organism or cell.

The aggregation, arrangement and bonding together of a set of components to form the anastral spindle in male meiotic cells.

The aggregation, arrangement and bonding together of a set of components to form the spindle during a meiotic cell cycle in males. An example of this is found in Drosophila melanogaster.

The aggregation, arrangement and bonding together of a set of components to form the spindle, the array of microtubules and associated molecules that serves to move duplicated chromosomes apart, in the absence of centrosomes. Formation is initiated by the nucleation of microtubules (MTs) in the vicinity of condensed chromatin. MTs then attach to and congress around the chromatin due to activity of microtubule motors. A bipolar spindle is formed by focusing of the terminal ends of the MT array into spindle poles by molecular motors and cross-linking proteins.

Any process involved in the maintenance of an internal steady state of magnesium ions at the level of a cell.

Any process involved in the maintenance of an internal steady state of divalent cations at the level of a cell.

Any process that modulates the rate, frequency, or extent of glucan biosynthesis. Glucan biosynthetic processes are the chemical reactions and pathways resulting in the formation of glucans, polysaccharides consisting only of glucose residues.

Any process that modulates the rate, extent or frequency of the chemical reactions and pathways involving carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y, as carried out by individual cells.

Any process that modulates the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of polysaccharides.

Any process that modulates the frequency, rate or extent of cellular macromolecule biosynthetic process.

Catalysis of the reaction: zeinoxanthin + NADPH + O2 + H+ = lutein + NADP+ + H2O. Adds a hydroxyl group to the epsilon ring of the alpha-carotene.

Catalysis of the reaction: a carotene + NADPH + O2 + H+ = a beta-ring hydroxylcarotene + NADP+ + H2O. Adds a hydroxyl group to the epsilon ring of the alpha-carotene.

Catalysis of the reaction: 1-hydroxypyrene + XSO3- = 1-pyrenylsulfate + HX.

Catalysis of the transfer of a sulfate group from 3'-phosphoadenosine 5'-phosphosulfate to the hydroxyl group of an acceptor, producing the sulfated derivative and 3'-phosphoadenosine 5'-phosphate.

Catalysis of a ring closure reaction.

Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
