One of the parties having the interest in the same matter.的谓语是什么?having作什么成分?

没有谓语 having the interest in the same matter 是现在分词短语充当定语修饰the parties 可以换谢成定语从句形似:one of the parties which have the interest in the same matter ..having the interest in the same matter是现在分词短语充当定语修饰the parties,句子主要成分剩下one of the parties.一个句子只有主语，没有谓语可以成立吗？
