Recombinant Human Phosphatidylserine synthase 1 (PTDSS1), partial | CSB-RP043054h | Cusabio

Alternative Name(s): Serine-exchange enzyme I

Gene Names: PTDSS1

Research Areas: Metabolism

Organism: Homo sapiens (Human)

AA Sequence: MASCVGSRTLSKDDVNYKMHFRMINEQQVEDITID

Source: E.coli

Tag Info: N-terminal GST-tagged

Expression Region: 1-35aa

Sequence Info: Partial

MW: 31.1 kDa

Purity: Greater than 90% as determined by SDS-PAGE.

Relevance: Catalyzes a base-exchange reaction in which the polar head group of phosphatidylethanolamine (PE) or phosphatidylcholine (PC) is replaced by L-serine. In mbranes, PTDSS1 catalyzes mainly the conversion of phosphatidylcholine. Also converts, in vitro and to a lesser extent, phosphatidylethanolamine.

Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20?/-80?. The shelf life of lyophilized form is 12 months at -20?/-80?.

Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4? for up to one week.

Function: Catalyzes a base-exchange reaction in which the polar head group of phosphatidylethanolamine (PE) or phosphatidylcholine (PC) is replaced by L-serine. In membranes, PTDSS1 catalyzes mainly the conversion of phosphatidylcholine. Also converts, in vitro and to a lesser extent, phosphatidylethanolamine.

Involvement in disease: Lenz-Majewski hyperostotic dwarfism (LMHD)

Subcellular Location: Endoplasmic reticulum membrane, Multi-pass membrane protein

Protein Families: Phosphatidyl serine synthase family

Tissue Specificity:

Paythway:

Form: Liquid or Lyophilized powder

Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.

Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20?/-80?. Our default final concentration of glycerol is 50%. Customers could use it as reference.
