It shows 100% activity toward L-glutamine, 70% toward D-glutamine, and 0% toward L-asparagine and D-asparagine.

Sucrose is used as a stabilizer.

It is stable in liquid form below 50°C (Fig.4) and remains stable at 37°C for at least four days (Fig.5). In powder form, it remains stable at 30°C for at least two weeks (Fig.6).

The optimal pH is 7.0, and the optimal temperature is 65°C.

The molecular weight is approximately 58 kDa (gel filtration), and it exhibits a heterodimeric structure composed of 45 kDa and 22 kDa subunits (SDS-PAGE).

It is useful for the determination of glutamine in clinical analysis.
