Glycerol-3-phosphate dehydrogenase is involved in glycerol catabolism. It converts the sn-glycerol 3-phosphate to glycerone phosphate; Uses FAD as cofactor; Localized in the cytoplasm; High confidence in function and specificity.

RNA polymerase ECF-type sigma factor; Sigma factors are initiation factors of transcription that promote the attachment of RNA polymerase to specific initiation sites (promoters) and are then released; They alter the specificity of promoter recognition; This family represents a group of sigma factors that are able to regulate extra cellular function (ECF). ECF-sigma factors all retain two features: the ability to respond to extra-cytoplasmic functions via the TonB-dependent transducer genes, and regulation by anti-sigma and anti-anti-sigma factors; Family membership.

Type I phosphodiesterase catalyzes the cleavage of phosphodiester and phosphosulphate bonds in various compounds such as NAD, deoxynucleotides and nucleotide sugars; Contains a signal peptide cleaved between the residues 26 and 27; Localized in the periplasmic space; Family membership.

Aquaporin Z; Channel that permits osmotically driven movement of water in both directions. It is involved in the osmoregulation and in the maintenance of cell turgor during volume expansion in rapidly growing cells. It mediates rapid entry or exit of water in response to abrupt changes in osmolarity; Belongs to the MIP/aquaporin (TC 1.A.8) family.

Glycerol enters the cell via the glycerol diffusion facilitator protein. This membrane protein facilitates the movement of glycerol across the cytoplasmic membrane. Belongs to the Major Intrinsinc Protein family which also includes aquaporin. Features six transmembrane helices. Localized in the cytoplasmic membrane; High confidence in function and specificity; Belongs to the MIP/aquaporin (TC 1.A.8) family.
