 339-408 6.83e-18

RNA recognition motif (RRM) superfamily; RRM, also known as RBD (RNA binding domain) or RNP (ribonucleoprotein domain), is a highly abundant domain in eukaryotes found in proteins involved in post-transcriptional gene expression processes including mRNA and rRNA processing, RNA export, and RNA stability. This domain is 90 amino acids in length and consists of a four-stranded beta-sheet packed against two alpha-helices. RRM usually interacts with ssRNA, but is also known to interact with ssDNA as well as proteins. RRM binds a variable number of nucleotides, ranging from two to eight. The active site includes three aromatic side-chains located within the conserved RNP1 and RNP2 motifs of the domain. The RRM domain is found in a variety heterogeneous nuclear ribonucleoproteins (hnRNPs), proteins implicated in regulation of alternative splicing, and protein components of small nuclear ribonucleoproteins (snRNPs).

5,10-methenyltetrahydrofolate synthetase; This enzyme, 5,10-methenyltetrahydrofolate synthetase, is also called 5-formyltetrahydrofolate cycloligase. Function of bacterial proteins in this family was inferred originally from the known activity of eukaryotic homologs. Recently, activity was shown explicitly for the member from Mycoplasma pneumonia. Members of this family from alpha- and gamma-proteobacteria, designated ygfA, are often found in an operon with 6S structural RNA, and show a similar pattern of high expression during stationary phase. The function may be to deplete folate to slow 1-carbon biosynthetic metabolism. [Central intermediary metabolism, One-carbon metabolism]
