This Pfam family contains the sigma-54 modulation protein family and the S30AE family of ribosomal proteins which includes the light- repressed protein (lrtA) (Swiss:P47908) [1]. [1]. 8063707. A light-repressed transcript found in Synechococcus PCC 7002 is. similar to a chloroplast-specific small subunit ribosomal. protein and to a transcription modulator protein associated with. sigma 54..

HPF/RaiA family ribosome-associated protein such as Bacillus subtilis ribosome hibernation promotion factor (HPF), which is required for dimerization of active 70S ribosomes into 100S ribosomes in stationary phase

This model includes a small protein encoded by one of two genes, both downstream of the gene rpoN for sigma 54, whose deletion leads to increased expression from sigma 54-dependent promoters. It also includes the N-terminal half of a light-repressed protein LtrA of Synechococcus PCC 7002 and the N-terminal region (after removal of the transit peptide) of a larger plastid-specific ribosomal protein of spinach. The member of this family from E. coli is now recognized as a protein at the interface between ribosomal large and small subunits, with about 1/3 as many copies per cell as the number of ribosomes.
