Zinc forms part of the active site and/or stabilizes the conformation of several enzymes. The protein metallothionein constitutes a zinc deposit from which the metal is transferred to enzymes. Zinc participates in the synthesis of nucleic acids and hence in the synthesis of proteins, principally through multi-enzyme pir 1-3 and DNA-dependent RNA polymerase, which are metallo-enzymes of zinc. Zinc is therefore necessary for normal growth, development, healing and ossification.
锌是几种酶活性位点的组成部分和/或能稳定其构象。蛋白质金属硫蛋白构成锌的储存库，金属从该储存库转移至酶。锌主要通过多酶pir 1 - 3和依赖DNA的RNA聚合酶（这两种都是锌金属酶）参与核酸合成，进而参与蛋白质合成。因此，锌对于正常生长、发育、愈合和骨化是必需的。
