Predicted protein sequence of AtRGP1 (GenBank
accession no. AF013627) and comparison with other RGP proteins. A,
Amino acid sequence alignment of AtRGP1, PsRGP1 (U31565), VuRGP
(AF005279), ZmRGP (U89897), and OsRGP using the MegAlign module of
DNAStar. The black regions represent amino acid differences between
AtRGP1 and the other RGPs. The overline highlights a putative
N-myristoylation site. The shaded box represents the
predicted UDP-Glc-binding domain U1 from cotton CelA. The open box is
the site of glycosylation as determined in sweet corn. Underlined are
the two pea tryptic peptides used to search the EST
database. B, Alignment of UDP-Glc-binding domains from
various organisms, as determined by Delmer and Amor (1995), with the
predicted binding domain of RGP.
