9.B.375. The SARS3b Protein (SARS3b) Family This family consists of several viral proteins, all fairly closely related in sequence. The SARS3b protein (9.B.375.1.1) is 154 aas, possibly with as many as 3 TMSs.
Examples:
TC#	Name	Organismal Type	Example
9.B.375.1.1	SARS3b protein of 154 aas and possibly as many as 3 (not very hydrophobic) TMSs.		SARS3b of severe acute respiratory syndrome-related (SARS) coronavirus

9.B.375.1.2	ORF3b of 114 aas and possibly 3 poorly hydrophobic TMSs. This protein is 90% identical to the one with TC#9.B.375.1.1		ORF3b of BtRf-BetaCoV/JL2012
