[ccp4bb] BBSRC-funded 34-month position working on integral membrane pyrophosphatases

2020-08-07 Thread Goldman, Adrian
I am looking for a research assistant to join the project. We are moving on from structural studies of the enzyme to functional studies (such as PELDOR and Nanion Surfer). Working with a postdoc in the lab, you will be an integral member of my team. We are a diverse group of about 15 scientis

Dear Paul, First and foremost, thanks a lot for your answer. It is very helpful to get some insight into what's going on with the software, and you explained it simply and exhaustively. I will check the overall quality of the model built in Coot that I used as an input for the last refinement

[ccp4bb] Structural Importance of Methionine

Dear All,I am working on structures where Methionine is important in binding of peptides to the MHC protein complex.Would anyone kindly like to share their knowledge about anything they find it important about this particular amino acid structurally? Sharing a paper or just few comments will be

Hi Samer, I came across this interesting article recently, that discusses the significance of unusually high content of Met in the polymerization inducing domain of spider silk protein ( https://www.nature.com/articles/s41467-019-12365-5). Methionines provide a 'mobilization' to the hydrophobic co

Hi Samer, In addition to what has been already mentioned to you, there are also the two well illustrated cases of methionine rich domains. - in the case of the M (for Met rich) domain of the Signal Recognition Particle protein SRP54/Ffh involved in promiscuous binding of the N-terminal hydrophobic

Hi Samer, Adding to Pascal’s list, calmodulin is another protein with many methionines that provide a flexible binding site. See this review as a starting point for reading about it: https://pubmed.ncbi.nlm.nih.gov/9923700/. Best, Rachelle __

Hi Samer, I solved a pair of structures in which a methionine rich amphipathic peptide extending from a coiled coil protein formed two different, fairly intimate crystal contacts in two different crystal forms (see Figure 3). It seems the methionine rich side of this peptide really wanted to be bu
