S. hygroscopicus Recombinant Protein

Specifications

Product Data
Species	S. hygroscopicus
Expression cDNA Clone or AA Sequence	Protein Sequence (showhide) Met1-Ile183
Buffer	Lyophilized from a 0.2 um filtered solution of PBS, pH 7.4.
Note	Recombinant Streptomyces hygroscopicus Phosphinothricin N-acetyltransferase is produced by our E.coli expression system and the target gene encoding Met1-Ile183 is expressed.
Storage	Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
Stability	12 months from date of despatch
Reference Data
Synonyms	Phosphinothricin N-acetyltransferase; PPT N-acetyltransferase; Phosphinothricin-resistance protein; bar
Summary	Phosphinothricin N-acetyltransferase (PAT) is an enzyme that acetylates the free NH2 group of L-phosphinothricin (L-PPT) in the presence of acetyl-CoA as a co-substrate. It is highly specific for L-PPT and does not acetylate other L-amino acids or structurally similar molecules. L-PPT is a glutamate analog that can inhibit glutamine synthetase activity in plants, resulting in the accumulation of ammonia to toxic levels and impairment of photosynthesis. The introduction of a PAT gene into a plant genome can confer resistance to glufosinate herbicide during post-emergent applications.
