Recombinant Cystatin C (Cys-C)

细胞色素 c cytochrome c

　　 广义的细胞色素 c是含有血红素 c的细胞色素之总称。通常是指主要存在于高等动植物、酵母、霉菌等线粒体中的细胞色素 c，起着传递电子的作用。为分子量约 1.3万的碱性蛋白质，还原型的吸收带为 550、 520、 415毫微米，氧化型为 407毫微米。α 因此很早便被研究，并获得结晶。不仅一级结构而且立体结构也已清楚（图 1）。其结构基本上是生物界共有的。由细胞色素 c氧化酶〔细胞色素（ a＋ a3 ）复合体〕氧化。在呼吸链中从细胞色素 c开始接受电子，各种还原酶都已清楚

Purification of the N- and C-Terminal Subdomains of Recombinant Heavy Chain Fragment C of Botulinum Neurotoxin Serotype C

The N-terminal and C-terminal portions of the heavy chain fragment C from botulinum neurotoxin serotype C [rBoNT(HC )] were expressed in Pichia pastoris and purified by ion-exchange chromotography (IEC). The N-terminal fragment, rBoNTC(Hc )-N

Expression of Recombinant Cytochromes c in E. coli

for proper folding and stability. However, significant advances in expression of recombinant cytochromes c have been made during the last decade. It has been shown that a single gene cluster, ccmA–H , is responsible for cytochrome c maturation in Escherichia
