Abstract
The analogous N proteins encoded by lambdoid bacteriophages lambda, 21, and 22 are very different in amino acid sequence, except at their carboxy-terminal ends. Since N lambda remains functional despite the deletion of most of its terminal region of homology to N21, that region of homology cannot represent a region of conserved function.
摘要
λ噬菌体、21噬菌体和22噬菌体编码的类似N蛋白，除了其羧基末端外，氨基酸序列差异很大。由于λ噬菌体的N蛋白尽管删除了其与21噬菌体N蛋白同源的大部分末端区域仍具有功能，因此该同源区域不可能代表保守功能区域。
