sulfur assimilation

Plants take up sulfate in their roots and reduce it to sulfide (see sulfur assimilation).

This enzyme participates in selenoamino acid metabolism and sulfur assimilation.

In biology, a sulfonucleotide reductase is actually a class of enzymes involved in reductive sulfur assimilation.

APS reductase, an enzyme of the sulfur assimilation pathway uses glutathione as electron donor.

In organisms that synthesize cysteine in sulfur assimilation such as bacteria and yeast, the transsulfuration pathway works in reverse.

Assimilative sulfate reduction (see also sulfur assimilation) in which sulfate (SO) is reduced by plants, fungi and various prokaryotes.

It plays a major role in the sulfur assimilation pathway: converting sulfite to a biologically useful sulfide, which can be incorporated into the organic compound homocysteine.

The uptake of sulfate by the roots and its transport to the shoot is strictly controlled and it appears to be one of the primary regulatory sites of sulfur assimilation.

It is not yet solved, whether sulfate itself or metabolic products of the sulfur assimilation (O-acetylserine, cysteine, glutathione) act as signals in the regulation of sulfate uptake by the root and its transport to the shoot, and in the expression of the sulfate transporters involved.
