Protein

Outer capsid protein lambda-2

Gene

L2

Organism
Reovirus type 1 (strain Lang) (T1L) (Mammalian orthoreovirus 1)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

Functioni

Outer capsid protein involved in mRNA capping. Catalyzes the last 3 enzymatic activities for formation of the 5' cap structure on the viral plus-strand transcripts, namely the RNA guanylyltransferase, RNA-7N- and RNA-2'O-methyltransferase activities (By similarity).By similarity

Catalytic activityi

GTP + (5')pp-Pur-mRNA = diphosphate + G(5')ppp-Pur-mRNA.
S-adenosyl-L-methionine + G(5')pppR-RNA = S-adenosyl-L-homocysteine + m7G(5')pppR-RNA.
