BUAP5A_271 is encoded by the BUAP5A_271 gene in Buchnera aphidicola (strain 5A), a bacterium that resides intracellularly in aphids like Acyrthosiphon pisum . Buchnera has undergone extensive genome reduction due to its obligate symbiosis, retaining genes critical for amino acid biosynthesis (e.g., tryptophan) while losing others unnecessary in aphid-host environments . The BUAP5A_271 gene is annotated as a multi-pass membrane protein, though its exact functional role remains unclear .
BUAP5A_271 is heterologously expressed in E. coli using standard recombinant protein protocols . Key production parameters include:
Tag Information: N-terminal or C-terminal tags (e.g., His-tag) are applied to facilitate purification .
Yield: Typically supplied in quantities of 50 µg, with custom amounts available .
BUAP5A_271 is utilized in ELISA assays to detect specific antibodies or study protein interactions. For example, recombinant proteins like this are critical for developing diagnostics targeting Buchnera-aphid symbiosis .
BUAP5A_271 serves as a model for studying gene loss and functional adaptation in symbiotic bacteria. Buchnera’s reduced genome highlights the trade-offs between retained essential functions and lost non-essential genes .
Despite its availability, BUAP5A_271’s precise biological function remains undefined. Key areas for further research include:
