    E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

  • 功能：
    In presence of calcium ions, it binds to surfactant phospholipids and contributes to lower the surface tension at the air-liquid interface in the alveoli of the mammalian lung and is essential for normal respiration.

    1. SP-A1 6A4 and SP-A2 1A5 genetic variants may influence the susceptibility to respiratory distress syndrome in late-preterm infants, independently of the effect of other perinatal factors. PMID: 27835691

    3. In a Dutch cohort study of unrelated patients with idiopathic or familial interstitial pneumonia genetic analysis of SFTPA2 three new mutations in exon 6 of SFTPA2: N210T, G231R, and N171Y were identified. None were found in the control group. PMID: 26568241

    25. We conclude that SP-A permeabilizes phospholipid membranes in an LPS-dependent and rough LPS-specific manner, that the effect is neither SP-A- nor species-specific, and that oxidative damage to SP-A abolishes its membrane destabilizing properties PMID: 16489761
    26. Residue 85 plays an important role in the structure and function of SP-A and is a major factor for the differences between SP-A1 and SP-A2 variants. PMID: 17580966
