A, B, C, D	PF20833	RNase E/G, Thioredoxin-like domain (RNase_E_G_Thio)	RNase E/G, Thioredoxin-like domain	Both RNase E and its homologue RNase G are endoribonucleases that play central roles in RNA processing. RNase E shows two globular domains. This entry represents the smaller domain, which shows a thioredoxin-like fold [1-3].	Domain
A, B, C, D	PF00575	S1 RNA binding domain (S1)	S1 RNA binding domain	The S1 domain occurs in a wide range of RNA associated proteins. It is structurally similar to cold shock protein which binds nucleic acids. The S1 domain has an OB-fold structure.	Domain
