| AHA | Halotolerant | 0.5 | 10.4 | 5.7 | 4.7 | [21] |
| AmyZ | Halotolerant | 1.5 | 15.4 | 9.7 | 5.7 | [23] |
| Amy13A | Halotolerant | 0.86 | 16.7 | 11.9 | 4.8 | [48] |
| AmyH | Halophile | 4 | 16.5 | 6.1 | 10.4 | [51] |
| α-amylaseA | Haloalkaliphilic | 2.5 | 24.3 | 5.4 | 18.9 | [52] |
The amino acid compositions of α-amylases were obtained from Genbank.
