RraA family protein such as regulator of ribonuclease activity A (RraA), which globally modulates RNA abundance by binding to RNase E and regulating its endonucleolytic activity, and 4-hydroxy-4-methyl-2-oxoglutarate (HMG) aldolase, which catalyzes the aldol cleavage of HMG into 2 molecules of pyruvate

regulator of ribonuclease activity A; This family includes a number of closely related sequences from certain enterobacteria. The E. coli member of this family has been characterized as a regulator of RNase E and its crystal structure has been analyzed. The broader subfamily which includes this equivalog, TIGR01935, was initially classified as a "hypothetical equivalog" with the name "regulator of ribonuclease activity A" based on the same evidence for this model. It now appears that, considering the second group of enterobacterial sequences within TIGR01935, the functional assignment is unsupported. THIS PROTEIN IS _NOT_ MenG, AKA S-adenosylmethionine: 2-demethylmenaquinone methyltransferase (EC 2.1.-.-). See the references characterizing this as a case of transitive annotation error.

ribonuclease activity regulator RraA family; RraA protein family is named after the regulator of ribonuclease activity A (RraA), a protein that binds to RNase E and inhibits RNase E endonucleolytic cleavages. Members also include proteins with other functions, like a 4-hydroxy-4-methyl-2-oxoglutarate/4-carboxy-4-hydroxy-2-oxoadipate (HMG/CHA) aldolase from Pseudomonas putida, which catalyzes the last step of the bacterial protocatechuate 4,5-cleavage pathway and the uncharacterized YER010Cp protein from yeast, an organism lacking RNAse E.

Aldolase/RraA; Members of this family include regulator of ribonuclease E activity A (RraA) and 4-hydroxy-4-methyl-2-oxoglutarate (HMG)/4-carboxy- 4-hydroxy-2-oxoadipate (CHA) aldolase, also known as RraA-like protein. RraA acts as a trans-acting modulator of RNA turnover, binding essential endonuclease RNase E and inhibiting RNA processing. RraA-like proteins seem to contain aldolase and/or decarboxylase activity either in place of or in addition to the RNase E inhibitor functions.

RraA famliy; The E. coli member of this family has been characterized as a regulator of RNase E and its crystal structure has been analyzed. This model was initially classified as a "hypothetical equivalog" expressing the tentative hypothesis that all members might have the same function as the E. coli enzyme. Considering the second clade of enterobacterial sequences within this family, that appears to be less tenable. The function of these sequences outside of the narrow RraA equivalog model (TIGR02998) remains obscure. All of these were initially annotated as MenG, AKA S-adenosylmethionine: 2-demethylmenaquinone methyltransferase (EC 2.1.-.-). See the references characterizing this as a case of transitive annotation error in the case of the E. coli protein. [Unknown function, General]

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.

(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
