cysteine desulfurase, catalytic subunit CsdA; Members of this protein family are CsdS. This protein, found Escherichia coli, Yersinia pestis, Photorhabdus luminescens, and related species, and related to SufS, works together with and physically interacts with CsdE (a paralog of SufE). CsdA has cysteine desulfurase activity that is enhanced by CsdE, a sulfur acceptor protein. This gene pair, although involved in FeS cluster biosynthesis, is not found next to other such genes as are its paralogs from the Suf or Isc systems.

family 2A encapsulin nanocompartment cargo protein cysteine desulfurase; Capsid-like encapsulin nanocompartments are commonly found in bacteria and archaea. Encapsulin nanocompartments, which are assembled from shell proteins, encapsulate various cargo proteins, typically peroxidases or ferritin-like proteins, to protect cells from oxidative stress caused by peroxide. Proteins of this family are cysteine desulfurases with an additional N-terminal encapsulation targeting sequence (~200 aa) that is necessary and sufficient for compartmentalization.

cysteine desulfurases, SufSfamily; This model represents a subfamily of NifS-related cysteine desulfurases involved in FeS cluster formation needed for nitrogen fixation among other vital functions. Many cysteine desulfurases are also active as selenocysteine lyase and/or cysteine sulfinate desulfinase. This subfamily is associated with the six-gene SUF system described in E. coli and Erwinia as an FeS cluster formation system during oxidative stress. The active site Cys is this subfamily resembles GHHC with one or both His conserved. [Biosynthesis of cofactors, prosthetic groups, and carriers, Other]

cysteine desulfurase family protein, VC1184 subfamily; This model describes a subfamily of probable pyridoxal phosphate-dependent enzymes in the aminotransferase class V family (pfam00266). The most closely related characterized proteins are active as cysteine desulfurases, selenocysteine lyases, or both; some are involved in FeS cofactor biosynthesis and are designated NifS. An active site Cys residue present in those sequences, in motifs resembling GHHC or GSAC, is not found in this family. The function of members of this family is unknown, but seems unlike to be as an aminotransferase. [Unknown function, Enzymes of unknown specificity]

Aspartate aminotransferase (AAT) superfamily (fold type I) of pyridoxal phosphate (PLP)-dependent enzymes. PLP combines with an alpha-amino acid to form a compound called a Schiff base or aldimine intermediate, which depending on the reaction, is the substrate in four kinds of reactions (1) transamination (movement of amino groups), (2) racemization (redistribution of enantiomers), (3) decarboxylation (removing COOH groups), and (4) various side-chain reactions depending on the enzyme involved. Pyridoxal phosphate (PLP) dependent enzymes were previously classified into alpha, beta and gamma classes, based on the chemical characteristics (carbon atom involved) of the reaction they catalyzed. The availability of several structures allowed a comprehensive analysis of the evolutionary classification of PLP dependent enzymes, and it was found that the functional classification did not always agree with the evolutionary history of these enzymes. Structure and sequence analysis has revealed that the PLP dependent enzymes can be classified into four major groups of different evolutionary origin: aspartate aminotransferase superfamily (fold type I), tryptophan synthase beta superfamily (fold type II), alanine racemase superfamily (fold type III), and D-amino acid superfamily (fold type IV) and Glycogen phophorylase family (fold type V).

Ornithine decarboxylase family. This family belongs to pyridoxal phosphate (PLP)-dependent aspartate aminotransferase superfamily (fold I). The major groups in this CD corresponds to ornithine decarboxylase (ODC), arginine decarboxylase (ADC) and lysine decarboxylase (LDC). ODC is a dodecamer composed of six homodimers and catalyzes the decarboxylation of tryptophan. ADC catalyzes the decarboxylation of arginine and LDC catalyzes the decarboxylation of lysine. Members of this family are widely found in all three forms of life.
