The chemical reactions and pathways involving the nonmetallic element sulfur or compounds that contain sulfur, such as the amino acids methionine and cysteine or the tripeptide glutathione.

The chemical reactions and pathways resulting in the formation of amino acids containing sulfur, comprising cysteine, methionine and selenocysteine.

The pathways by which inorganic sulfate is processed and incorporated into sulfated compounds.

A multisubunit iron flavoprotein, which in yeast is composed of 2 alpha and 2 beta subunits. Catalyzes the reduction of sulfite to sulfide.

A multisubunit iron flavoprotein, which in yeast is composed of 2 alpha and 2 beta subunits. Catalyzes the reduction of sulfite to sulfide.

A vacuole that has both lytic and storage functions. The fungal vacuole is a large, membrane-bounded organelle that functions as a reservoir for the storage of small molecules (including polyphosphate, amino acids, several divalent cations (e.g. calcium), other ions, and other small molecules) as well as being the primary compartment for degradation. It is an acidic compartment, containing an ensemble of acid hydrolases. At least in S. cerevisiae, there are indications that the morphology of the vacuole is variable and correlated with the cell cycle, with logarithmically growing cells having a multilobed, reticulated vacuole, while stationary phase cells contain a single large structure.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

A dense aggregation in the cytosol composed of proteins and RNAs that appear when the cell is under stress.

The part of a cell encompassing the cell cortex, the plasma membrane, and any external encapsulating structures.
