General description
作为脂质运载蛋白家族的一员，βLg是由162个氨基酸组成的小分子蛋白质，分子量∼18,400 Da，具有八链β-桶状（链 A-H）结构，后接一个含有3转角的α-螺旋和构成一部分二聚化界面的最后一条β-链（链 I）。
奶牛乳汁中含有蛋白质 β-乳球蛋白 (BLG)。它天然存在于一些遗传变异中，最普遍的牛变异称为 BLG A 和 BLG B。
Application
β-乳球蛋白用于通过等电聚焦电泳法鉴定牛奶中的κ-酪蛋白的遗传变异体。
β牛奶β-乳球蛋白已用于：
- 作为校准剂校准TriWave设备。
- 作为标准品，用于通过反相高效液相色谱(HPLC)检测和定量牛奶中的β-乳球蛋白
- 蛋白酶样品的纯化和分子量测定
Biochem/physiol Actions
ββ-乳球蛋白(β-lg)具有热致凝胶化特性。它还具有抗病毒、抗癌和降胆固醇作用。ββ-乳球蛋白可结合视黄醇和长链脂肪酸，参与脂肪酸的吸收和代谢。

The crystal structures of beta-lactoglobulin genetic variants A and B have been determined in the orthorhombic space group C222(1) (lattice Y) by X-ray diffraction at 2.0 A and 1.95 A resolution, respectively. The structural comparison shows that both variants exhibit

We use time-dependent fluorescence Stokes shift (TDFSS) information to study the fluctuation rates of the lipocalin, beta-lactoglobulin A in the vicinity of an encapsulated coumarin 153 molecule. The system has three unique dielectric environments in which the fluorophore binds. We

Interactions between beta-lactoglobulin (BLG) in its monomeric form and a wide range of aroma compounds were investigated by Fourier transform infrared (FT-IR) and 2D nuclear magnetic resonance (NMR) spectroscopies. A screening of the ligands was carried out by FT-IR through
