Abstract
We have characterized three different soybean (Glycine max) mRNAs that encode apoproteins of extensins, a family of cell wall hydroxyproline-rich glycoproteins (HRGPs). These transcripts encoded distinctive Tyr-rich proteins containing characteristic Ser-Pro4 sequences organized in higher-order repetitive units. The first transcript encoded an extensin SbHRGP-1 containing the 16-amino acid repeat Ser-Pro4-Ser-Pro-Ser-Pro4-Tyr-Val-Tyr-Lys, with Val occasionally replaced by Ile or Tyr. The second transcript encoded the SbHRGP-2 protein containing the 16-amino acid repeat Ser-Pro4-Ser-Pro-Ser-Pro4-Tyr-Tyr-Tyr-Lys/His. The third transcript encoded the SbHRGP-3 protein containing a variant of 9- or 10-amino acid canonical repeats: Ser-Pro4-Tyr-Lys-Tyr-Pro, Ser-Pro5-Tyr-Lys-Tyr-Pro, and Ser-Pro4-Val-Tyr-Lys-Tyr-Lys, respectively. The dramatic amino acid substitutions in the Tyr-rich blocks (Tyr-X-Tyr-Lys) among these HRGPs indicate that each SbHRGP may have a different function in cell wall architecture.
