I [auth P]	PF00886	Ribosomal protein S16 (Ribosomal_S16)	Ribosomal protein S16	-	Family
H [auth O]	PF00312	Ribosomal protein S15 (Ribosomal_S15)	Ribosomal protein S15		Domain
E [auth L], F [auth M], G [auth N]	PF00164	Ribosomal protein S12/S23 (Ribosom_S12_S23)	Ribosomal protein S12/S23	This protein is known as S12 in bacteria and archaea and S23 in eukaryotes.	Domain
E [auth L], F [auth M], G [auth N]	PF02330	Mitochondrial glycoprotein (MAM33)	Mitochondrial glycoprotein	This mitochondrial matrix protein family contains members of the MAM33 family which bind to the globular 'heads' of C1Q. It is thought to be involved in mitochondrial oxidative phosphorylation and in nucleus-mitochondrion interactions [1].	Domain
D [auth K]	PF00411	Ribosomal protein S11 (Ribosomal_S11)	Ribosomal protein S11	-	Family
B [auth C]	PF00189	Ribosomal protein S3, C-terminal domain (Ribosomal_S3_C)	Ribosomal protein S3, C-terminal domain	This family contains a central domain Pfam:PF00013, hence the amino and carboxyl terminal domains are stored separately. This is a minimal carboxyl-terminal domain. Some are much longer.	Domain
L [auth W]	PF14943	Mitochondrial ribosome subunit S26 (MRP-S26)	Mitochondrial ribosome subunit S26	-	Family
