You would need to incorporate as much information you can find as possible to make the 'best' prediction of domain boundaries. Typically, I would put together all the following information in one multiple sequence alignment to design domain constructs for structural studies. - Known structural

In case someone do not know this feature or how to set it up, you can choose to get the daily digest version of CCP4BB so that your mail box will not be filled with mails that you can't find time to read individually. I have just changed my settings at JISCMAIL web site. You would have to click

Hi Tania, A classical way of superimposing two structures is to use lsq_e and lsq_i commands in O . You can specify the regions that you want to match and visualize the superimposed structures right away to see if they make sense or not. O will also give you a pairwise sequence alignment and RM

I don't know much about Pichia expression system. You can consult glycobiologists if you are 100% sure that no mistake was made during the experiments. Our lab has been using Drosophila S2 insect cell expression system. With this system, you can maintain cell culture using roller bottles or fl

There are many cases in literature where the removal of N-linked glycosylations sites reduced the expression levels of secreted proteins. I would recommend removal of the N-linked glycans by enzymes (endo H, PNGase F, etc.) using the wild-type proteins you have obtained and then run a gel or mas

Hi Hongmin, I have used the anti-penta-His HRP conjugate antibody from Qiagen, and it works very well. It comes as a kit which includes a special blocking buffer. You don't need to use any secondary antibody, so it saves time. But you can only use the diluted solution 1-2 times within 1-2 week
