The Fig. 1 (Wang, O'Rear, Stollar) of Mutagenesis of the Sinbis nsP1 Protein etc. represents the deletions of conserved sequences within the Sindbis virus nsP1. The changes to the His(39), Arg(91), Asp(94), or Tyr(249) to Ala resulted in the loss of MTase activity and the ability of the virus to cause infection. Although changes, Ile(369) to Val, to the conserved amino acids did not affect MTase or infection; larger deletions (between 442 and 492) led to a complete loss in the MTase activity. Table 1 represents the results of the mutations on various clones to express MTase activity.
