Protein Family Models

This domain often occurs at the C-terminus of proteins containing Pfam:PF02482. (from Pfam)

Date:

2024-08-14

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 HMM identifies ribosome hibernation-promoting factors. In Mycobacterium tuberculosis and many other species, just one protein is hit, called HPF. In Escherichia coli K-12, this HMM identifies two paralogs, NP_417670.1 (called HPF) and NP_417088.1 (called either YfiA or RaiA), more closely related to each other (about 40 percent identity) than either is to the Mycobacterium tuberculosis protein (NP_217758.1).Hibernation is the process of suppressing protein translation by the dimerization of two ribosomes into a 100S hibernation complex. HPF promotes this dimerization.
