概述 描述 Recombinant Human Phosphoserine Phosphatase is produced by our E.coli expression system and the target gene encoding Met1-Glu225 is expressed with a 6His tag at the C-terminus. 别名 Phosphoserine Phosphatase, PSP, PSPase, L-3-Phosphoserine Phosphatase, O-Phosphoserine Phosphohydrolase, PSPH 形态 Supplied as a 0.2 μm filtered solution of 50mM Tris, 250mM NaCl, 50mM Imidazole, pH 8.5 . 来源 E.coli 氨基酸序列 MVSHSELRKLFYSADAVCFDVDSTVIREEGIDELAKICGVEDAVSEMTRRAMGGAVPFKAALTER LALIQPSREQVQRLIAEQPPHLTPGIRELVSRLQERNVQVFLISGGFRSIVEHVASKLNIPATNV FANRLKFYFNGEYAGFDETQPTAESGGKGKVIKLLKEKFHFKKIIMIGDGATDMEACPPADAFIG FGGNVIRVKDNAKWYITDFVELLGELEELEHHHHHH 内毒素水平 Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test. Accession # P78330 性能 背景 Phosphoserine phosphatase (PSP) is an enzyme that belongs to the serB family. PSPH catalyzes magnesium-dependent hydrolysis of L-phosphoserine and is also involved in an exchange reaction between L-serine and L-phosphoserine. The reaction mechanism proceeds via the formation of a phosphoryl-enzyme intermediates. Deficiency of this protein is thought to be linked to Williams syndrome. A disorder that results in pre- and postnatal growth retardation, moderate psychomotor retardation and facial features suggestive of Williams syndrome. 保存方法 Store at < -20°C, stable for 6 months after receipt. Please minimize freeze-thaw cycles. 纯度 Greater than 95% as determined by reducing SDS-PAGE.
