Vne I

Description

Recognition site and hydrolysis position:

Source: An E.coli strain, that carries the cloned gene VneI from Vibrio nereis 18
Unit definition:
One unit of the enzyme is the amount required to hydrolyze 1 μg of Lambda DNA in 1 hour at 37°C in a total reaction volume of 50 μl.
Assayed on:
Lambda DNA
Optimal SE-buffer: SE-buffer O
