TABLE 3.
Specific activities of HSS encoding cDNA sequences from various Convolvulaceae species
| Species | Specific activity (pkat·mg−1) | PAs | PA type | |
|---|---|---|---|---|
| Glycine buffer | Borate buffer | |||
| Ipomoea neei | 1040* | n.a. | + | Ipangulines |
| Ipomoea alba | 1544 (12%) | 46 (13%) | − | Necine base |
| Distimake quinquefolius ind. 1 | 3543 (3%) | 482 (6%) | + | Lycopsamine |
| D. quinquefolius ind. 2 | 163 (23%) | Not active | + | Lycopsamine |
| Camonea umbellata | Not active | Not active | − | − |
Note: The enzymes ability to produce homospermidine in glycine‐ and borate‐based assay buffer is given. In bracket, relative standard deviation of three assays are given. Specific activities labeled with an asterisk (*) refer to Kaltenegger et al. (2013).
