Description

Introduction to Recombinant Lactobacillus acidophilus Cysteine--tRNA ligase (cysS)

Recombinant Lactobacillus acidophilus Cysteine--tRNA ligase, encoded by the gene cysS, is an enzyme that plays a crucial role in the process of protein synthesis. This enzyme is responsible for attaching the amino acid cysteine to its corresponding transfer RNA (tRNA) molecule, which is essential for incorporating cysteine into proteins during translation. The recombinant form of this enzyme is produced through genetic engineering techniques, allowing for its large-scale production and purification for various applications in research and biotechnology.

Function and Mechanism

Cysteine--tRNA ligase, or cysteinyl-tRNA synthetase, catalyzes the reaction between cysteine and tRNA to form cysteinyl-tRNA. This process involves two main steps: the activation of cysteine to form an aminoacyl-adenylate intermediate, followed by the transfer of cysteine to tRNA, resulting in the formation of cysteinyl-tRNA. This enzyme is highly specific for cysteine and ensures that cysteine is accurately incorporated into proteins during translation.

Characteristics of Recombinant Lactobacillus acidophilus Cysteine--tRNA ligase

  • Purity: The recombinant enzyme is typically purified to a high degree, often greater than or equal to 85% purity as determined by SDS-PAGE .

  • Storage Conditions: For long-term storage, the enzyme should be conserved at -20°C .

  • Organism: The enzyme is derived from Lactobacillus acidophilus, a species commonly used in probiotics and known for its health benefits .

Product Specs

Form
Lyophilized powder
Note: While we prioritize shipping the format currently in stock, please specify your format preference during order placement for customized preparation.
Lead Time
Delivery times vary depending on the purchasing method and location. Please contact your local distributor for precise delivery estimates.
Note: Standard shipping includes blue ice packs. Dry ice shipping requires prior arrangement and incurs additional charges.
Notes
Avoid repeated freeze-thaw cycles. Store working aliquots at 4°C for up to one week.
Reconstitution
Centrifuge the vial briefly before opening to consolidate the contents. Reconstitute the protein in sterile, deionized water to a concentration of 0.1-1.0 mg/mL. For long-term storage, we recommend adding 5-50% glycerol (final concentration) and aliquoting at -20°C/-80°C. Our standard glycerol concentration is 50%, which can be used as a reference.
Shelf Life
Shelf life depends on various factors including storage conditions, buffer composition, temperature, and protein stability. Generally, liquid formulations have a 6-month shelf life at -20°C/-80°C, while lyophilized formulations have a 12-month shelf life at -20°C/-80°C.
Storage Condition
Upon receipt, store at -20°C/-80°C. Aliquoting is essential for multiple uses. Avoid repeated freeze-thaw cycles.
