摘要大西洋肋贻贝Geukensia (Modiolus)demissa 通过纺粘性足丝线将自身附着在潮汐盐沼中的绳草和其他坚硬物体的根部。从贻贝的足部分离出大量明显存在于线的粘附斑中的蛋白质前体。该蛋白的表观分子量为130000,pI为8.1,含有高比例的Gly、Glu/Gln、Lys和3,4-二羟基苯基-L-丙氨酸(DOPA)。胰蛋白酶肽的序列表明重复基序的模式,例如:Gly-DOPA-Lys 和 X-Gly-DOPA-Y-Z-Gly-DOPA/Tyr-Lys,其中 X 是八肽中的 Thr 或 Ala,九肽中是 Gln-Thr。 Y是可变的,但通常不是疏水性的; Z通常是Pro或4-反式羟脯氨酸(Hyp)。蛋白质中 δ-羟基赖氨酸的 Pro-Gly 和 Hyp-Gly 序列的存在让人想起典型的胶原蛋白;然而,该蛋白质对梭菌胶原酶不稳定,胶原蛋白也不与针对贻贝蛋白的抗体发生交叉反应。与典型的胶原蛋白不同,甘氨酸可能仅出现在这种不寻常的贻贝蛋白中的每 4 个或 5 个残基处。
SummaryThe Atlantic ribbed musselGeukensia (Modiolus)demissa attaches itself to the roots of cord grass and other hard objects in tidal salt marshes by spinning adhesive byssal threads. The precursor of a protein apparently present in the adhesive plaques of the threads was isolated in quantity from the foot of the mussel. The protein has an apparent molecular weight of 130000, a pI of 8.1, and contains a high proportion of Gly, Glu/Gln, Lys and 3,4-dihydroxyphenyl-l-alanine (DOPA). Sequence of tryptic peptides suggests a pattern of repeated motifs, such as: Gly-DOPA-Lys, and X-Gly-DOPA-Y-Z-Gly-DOPA/Tyr-Lys, where X is Thr or Ala in octapeptides and Gln-Thr in nonapeptides. Y is variable, but more often than not hydrophobic; and Z is frequently Pro or 4-trans-hydroxyproline (Hyp). The presence of Pro-Gly and Hyp-Gly sequences of δ-hydroxylysine in the protein is reminiscent of typical collagens; however, the protein is not labile to clostridial collagenase, nor does collagen cross-react with antibodies raised against the mussel protein. Unlike typical collagens, Gly probably occurs only at every 4th or 5th residue in this unusual mussel protein.
