How to determine the amino acid sequence from the carboxy terminus of the protein or peptidePURPOSE: To determine amino acid sequence from a C end of protein without using enzyme by making free amino acid into acetyl and extracting and identifying oxazolon derivative from amino acid of acetyl...
A vital function of the immune system is to detect alterations in tissue homeostasis and respond in a context-dependent manner. To achieve this, immune and stromal cells, particularly those located at barrier sites, express a diverse range of germline-encoded receptors termed pattern recognition rece...

Can we one day use parts to create a whole?; (B) The main reason why we would like to control living systems is to control how one cell behaves and in this way, determine what it does e.g. differentiation. The tools to achieve such fates are only beginning to come of ...

Explain several laboratory methods used to determine viable and total cell counts in populations undergoing exponential growth Describe examples of cell division not involving binary fission, such as budding or fragmentation Describe the formation and characteristics of biofilms ...
Loops in the axial channels of ClpAP and other AAA+ proteases bind a short peptide degron connected by a linker to the N- or C-terminal residue of a native protein to initiate degradation. ATP hydrolysis then powers pore-loop movements that translocate these segments through the channel until...

Comparing to a generic two-state model, our models can distinguish class I from class II MHCs and correlate their structural parameters with the TCR/pMHC’s potency to trigger T cell activation. The models are tested by mutagenesis using an MHC and a TCR mutated to alter conformation changes....
We determine a second structure at 3.2 Å resolution with the phosphate analog BeFx bound with ADP to Arp3 and ATP bound to Arp2. In this ADP-BeFx transition state the outer domain of Arp3 is rotated 2° toward the mother filament compared with the ADP state and makes slightly ...
