Two contiguous mcp genes, mcpA and mcpB, transcribed from the same DNA strand and capable of encoding methyl-accepting chemotaxis proteins (Mcp) have been isolated from Rhodobacter capsulatus (Rc), sequences and overexpressed in Escherichia coli (Ec). The deduced proteins (McpA, 69 171 Da; McpB, 81 629 Da) show a structure similar to that of Ec Mcp. The products of mcpA and mcpB, overproduced in Ec, were recognized by anti-Ec Mcp (Trg) antibodies.
已从荚膜红细菌（Rc）中分离出两个相邻的mcp基因，即mcpA和mcpB，它们从同一条DNA链转录而来，能够编码甲基接受趋化蛋白（Mcp），并对其进行了测序，还在大肠杆菌（Ec）中进行了过表达。推导的蛋白质（McpA，69 171 Da；McpB，81 629 Da）显示出与Ec Mcp相似的结构。在Ec中过量产生的mcpA和mcpB产物可被抗Ec Mcp（Trg）抗体识别。
