Flavoprotein; This family contains diverse flavoprotein enzymes. This family includes epidermin biosynthesis protein, EpiD, which has been shown to be a flavoprotein that binds FMN. This enzyme catalyzes the removal of two reducing equivalents from the cysteine residue of the C-terminal meso-lanthionine of epidermin to form a --C==C-- double bond. This family also includes the B chain of dipicolinate synthase a small polar molecule that accumulates to high concentrations in bacterial endospores, and is thought to play a role in spore heat resistance, or the maintenance of heat resistance. dipicolinate synthase catalyzes the formation of dipicolinic acid from dihydroxydipicolinic acid. This family also includes phenyl-acrylic acid decarboxylase (EC:4.1.1.-).

phosphopantothenoylcysteine decarboxylase / phosphopantothenate--cysteine ligase; This model represents a bifunctional enzyme that catalyzes the second and third steps (cysteine ligation, EC 6.3.2.5, and decarboxylation, EC 4.1.1.36) in the biosynthesis of coenzyme A (CoA) from pantothenate in bacteria. In early descriptions of this flavoprotein, a ts mutation in one region of the protein appeared to cause a defect in DNA metaobolism rather than an increased need for the pantothenate precursor beta-alanine. This protein was then called dfp, for DNA/pantothenate metabolism flavoprotein. The authors responsible for detecting phosphopantothenate--cysteine ligase activity suggest renaming this bifunctional protein coaBC for its role in CoA biosynthesis. This enzyme contains the FMN cofactor, but no FAD or pyruvoyl group. The amino-terminal region contains the phosphopantothenoylcysteine decarboxylase activity.

phosphopantothenoylcysteine decarboxylase, streptococcal; In most bacteria, a single bifunctional protein catalyses phosphopantothenoylcysteine decarboxylase and phosphopantothenate--cysteine ligase activities, sequential steps in coenzyme A biosynthesis (see TIGR00521). These activities reside in separate proteins encoded by tandem genes in some bacterial lineages. This model describes proteins from the genera Streptococcus and Enterococcus homologous to the N-terminal region of TIGR00521, corresponding to phosphopantothenoylcysteine decarboxylase activity.

of your query sequence and the protein sequences used to curate the domain model,
where hash marks (#) above the aligned sequences show the location of the conserved feature residues.

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits

Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
