Abstract
No periplasmic binding protein has been demonstrated for the ATP-binding cassette (ABC)-type cobalamin transporter BtuCD. New mutations (btuF) are described that affect inner-membrane transport. The BtuF protein has a signal sequence and resembles the periplasmic binding proteins of several other ABC transporters.
摘要
尚未证实ATP结合盒（ABC）型钴胺素转运蛋白BtuCD存在周质结合蛋白。本文描述了影响内膜转运的新突变（btuF）。BtuF蛋白具有信号序列，并且类似于其他几种ABC转运蛋白的周质结合蛋白。
