This domain is found in the virulence regulatory factor CvfB from Streptococcus pneumoniae and in similar proteins predominantly found in Firmicutes. CvfB is composed of three consecutive S1 RNA-binding domains and a winged-helix (WH) domain (Pfam:PF17783). This entry represents the second S! domain, an RNA-binding module that adopts the typical S1 fold that consists of a five-stranded, antiparallel beta-sheet forming a beta-barrel [1].	Domain
A	PF17783	CvfB-like winged helix domain (CvfB_WH)	CvfB-like winged helix domain	This winged helix domain is found in RNA-binding proteins such as CvfB [1].	Domain
A	PF13509	S1 domain (S1_2)	S1 domain	The S1 domain was originally identified as a repeat motif in the ribosomal S1 protein. It was later identified in a wide range of proteins. The S1 domain has an OB-fold structure. The S1 domain is involved in nucleic acid binding.	Domain
A	PF21191	CvfB first S1-like domain (CvfB_1st)	CvfB first S1-like domain	CvfB is a conserved regulatory protein important for the virulence of Staphylococcus aureus [1]. This entry represents the first of three S1-like OB-fold domains.	Domain
