Table II.
Relative amounts of labeled monosaccharides fractionated by cellulose and silica TLCs following acid hydrolysis of the ethanol-insoluble material from wild-type and mur4 elongating stem segments incubated in [14C]Glc
| Monosaccharide | Wild Type | mur4 |
|---|---|---|
| (a) Cellulose | ||
| Xyl | 13 ± 0.4 | 13 ± 0.5 |
| Ara | 12 ± 0.8 | 5.4 ± 0.1 |
| Glc | 22 ± 4.1 | 21 ± 4.6 |
| Gal | 40 ± 1.6 | 48 ± 3.9 |
| Uronic acids | 14 ± 1.8 | 14 ± 1.2 |
| (b) Silica | ||
| Xyl | 13 ± 0.6 | 14 ± 0.7 |
| Ara | 13 ± 0.5 | 5.7 ± 0.4 |
| Glc + Gal + GlcUA | 57 ± 1.9 | 64 ± 0.9 |
| GalUA | 17 ± 2.0 | 17 ± 0.9 |
Data are the mean of three samples of four stem segments each ± sd. The TLC system (b) was used to separate GlcUA from GalUA.
