| Abstract: | The article presents a study on the use of Patterson vectors molecular-replacement (PVMR) method in tracking helix fragments. It states that PVMR is calculated by equating a search model in a real space with Patterson cross and self vectors. It mentions that the equal matches of Patterson vectors are added to get the signal-to-noise ratio. Moreover, findings of the study show that PVMR is suitable in setting small helix fragments as structural root for molecular substitution. |
