glycyl radical enzyme family protein such as ribonucleotide reductase (RNR) and pyruvate formate lyase (PFL), which have diverged from a common ancestor. They have a structurally similar ten-stranded alpha-beta barrel domain that hosts the active site, and are radical enzymes. RNRs are found in all organisms and provide the only mechanism by which nucleotides are converted to deoxynucleotides. RNRs are separated into three classes based on their metallocofactor usage. Class I RNRs use a diiron-tyrosyl radical while Class II RNRs use coenzyme B12 (adenosylcobalamin, AdoCbl). Class III RNRs use an FeS cluster and S-adenosylmethionine to generate a glycyl radical. PFL, an essential enzyme in anaerobic bacteria, catalyzes the conversion of pyruvate and CoA to acteylCoA and formate in a mechanism that uses a glycyl radical.

Pyruvate formate lyase 2 and related enzymes; This family includes pyruvate formate lyase 2 (PFL2), B12-independent glycerol dehydratase (DhaB) and the alpha subunit of benzylsuccinate synthase (BssA), all of which have a highly conserved ten-stranded alpha/beta barrel domain, which is similar to those of PFL1 (pyruvate formate lyase 1) and RNR (ribonucleotide reductase). Pyruvate formate lyase catalyzes a key step in anaerobic glycolysis, the conversion of pyruvate and CoenzymeA to formate and acetylCoA. DhaB catalyzes the first step in the conversion of glycerol to 1,3-propanediol while BssA catalyzes the first step in the anaerobic mineralization of both toluene and m-xylene.

choline trimethylamine-lyase; Members of this family, homologs to pyruvate formate-lyases and benzylsuccinate synthases, are glycine radical enzymes that appear to act as choline TMA-lyase, that is, to perform a C-N bond cleavage turning choline into trimethylamine (TMA) plus acetaldehyde. The gene symbol is cutC, for choline utilization. The activase, CutD, is a radical SAM enzyme. [Energy metabolism, Amino acids and amines]

Click on the triangle to view details about the feature, including a multiple sequence alignment
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.
The thumbnail image, if present, provides an approximate view of the feature's location in 3 dimensions.

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
(labeled illustration).
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.
click on the bars or triangles to view your query sequence embedded in a multiple sequence alignment of the proteins used to develop the corresponding domain model.
The table lists conserved domains identified on the query sequence. Click on the plus sign (+) on the left to display full descriptions, alignments, and scores.
Click on the domain model's accession number to view the multiple sequence alignment of the proteins used to develop the corresponding domain model.

(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
advanced search options)
