Catabolite Activator Protein (blue) bound to a piece of DNA (red). In cell biology, catabolite activator protein (CAP), which is also known as cAMP receptor protein (CRP), is a trans-acting transcriptional activator in bacteria that effectively catalyzes the initiation of DNA transcription by interacting with RNA polymerase in a way that causes the DNA to bend.
[94] 40S and 60S are light and heavy components of the ribosome, 80S is the assembled ribosome bound to mRNA, eIF4F is a translation initiation factor, PABC1 is the Poly-A binding protein, and "cap" is the mRNA cap structure needed for mRNA circularization (which can be the normal m7G-cap or modified A-cap).
5' cap structure. A 5' cap (also termed an RNA cap, an RNA 7-methylguanosine cap, or an RNA m 7 G cap) is a modified guanine nucleotide that has been added to the "front" or 5' end of a eukaryotic messenger RNA shortly after the start of transcription. The 5' cap consists of a terminal 7-methylguanosine residue that is linked through a 5'-5 ...
Heat shock proteins are also believed to play a role in the presentation of pieces of proteins (or peptides) on the cell surface to help the immune system recognize diseased cells. [22] The major HSPs involved in the HSR include HSP70, HSP90, and HSP60. [5] Chaperones include the HSP70s and HSP90s while HSP60s are considered to be chaperonins. [17]
The enzyme aminocyclopropane-1-carboxylic acid synthase (ACC synthase, ACS) (EC 4.4.1.14) catalyzes the synthesis of 1-Aminocyclopropane-1-carboxylic acid (ACC), a precursor for ethylene, from S-Adenosyl methionine (AdoMet, SAM), an intermediate in the Yang cycle and activated methyl cycle and a useful molecule for methyl transfer:
Capillary electrophoresis (CE) is a family of electrokinetic separation methods performed in submillimeter diameter capillaries and in micro- and nanofluidic channels.Very often, CE refers to capillary zone electrophoresis (CZE), but other electrophoretic techniques including capillary gel electrophoresis (CGE), capillary isoelectric focusing (CIEF), capillary isotachophoresis and micellar ...
SlideShare was officially launched on October 4, 2006. Rashmi Sinha , the CEO and co-founder of SlideShare was named among the world's Top 10 Women Influencers in Web 2.0 by Fast Company . [ 5 ] Jonathan Boutelle [ 6 ] was the CTO of SlideShare and came up with the initial idea behind the website.
The molecular weights of these proteins are 87, 72 and 62 kiloDaltons, respectively. [50] The AAV capsid is composed of a mixture of VP1, VP2, and VP3 totaling 60 monomers arranged in icosahedral symmetry in a ratio of 1:1:10, [ 51 ] with an empty mass of approximately 3.8 MDa . [ 52 ]
