The collection of known 5 S rRNA primary structures is enriched with the sequences from three mollusca, the snails Helix pomatia and Arion rufus, and the mussel Mytilus edulis. The three sequences can be fitted in a five-helix secondary structure model previously shown (De Wachter et al. (1982) Biochimie 64, 311-329) to apply to all 5 S RNAs regardless of their origin. One of the helices in this model can undergo a bulge-internal loop transition. Within the metazoan kingdom, the dimensions of each helix and loop are rigidly conserved, except for one helix which can comprise either 6 or 7 base pairs.
已知的5S rRNA一级结构集合中富含来自三种软体动物的序列,即蜗牛玛瑙螺和红蛞蝓,以及贻贝紫贻贝。这三个序列可以拟合到先前显示的(德瓦赫特等人,(1982年)《生物化学》64卷,311 - 329页)适用于所有5S RNA(无论其来源如何)的五螺旋二级结构模型中。该模型中的一个螺旋可以经历凸起 - 内环转变。在后生动物界中,每个螺旋和环的尺寸严格保守,除了一个螺旋可以包含6或7个碱基对。
