A scanning tunneling microscopy (STM) investigation of complex formation between cytochrome P450(cam) and putidaredoxin.
We have previously reported the scanning tunnelling microscopy (STM) imaging under buffer of the heme monooxygenase cytochrome P450(cam) from Pseudomonas putida [Faraday Discuss. 116 (2000) 1]. We describe here the adsorption and STM imaging under buffer of complexes of a mutant of cytochrome P450(cam), K344C, and wild-type putidaredoxin (Pdx) on gold(111). The images of Pdx on its own on gold(111) are not uniform, presumably due to multiple orientations of protein adsorption because of the p...Expand abstract
