Alpha helix

subunit. Each domain contains several beta sheets in between anywhere between two to four alpha helices. Q3) Most of the β sheets are parallel, although there are a few antiparallel beta stands in the large domains. The α helices are located on either side of the beta sheets and are fairly close together on either site. Q4) The α helices and the β strands are connected by loops made of amino acids. Q5) There is a significant amount of space, and thus a large interface between the subunits that form dimers. The interface consists of a few loops and a few protruding amino acid side chains. Q6) The interface between subunits probably contains the binding site for activators and inhibitors. Q7) Since most of the effector molecules have negatively charged atoms (such as ADP with the negatively charged oxygen atoms on the phosphate groups), it is likely that positively charged residues will need to bind to them. Since many basic amino acids have side chains that are positive under cellular conditions, it is likely that basic amino acids will bind to these…

1. Most aquaporins have a similar structural arrangement, consisting of a similar fold. This fold contains helices encasing a small water-conducting channel where water is able to arrange in a singular line. There are cytoplasmic and extracellular loops immersing into the membrane through opposing sides, and form two smaller helices creating a psedo transmembrane segment. Within the membrane, there are four aquaporin molecules forming a homo-tetramer, creating a fifth channel; the channel is…

This bond that the soldiers formed helped them to survive, and helped the men of Alpha Company to cope with the war after they returned to the United States. "The bond that men form with each other in the heat of battle is incomprehensible to those who have not experienced warfare for themselves...You make close friends. You become part of a tribe and you share the same blood - you give it together, you take it together." (O'Brien, 192) This bond of friendship helps the men of Alpha…

All throughout grade school, I have learned how African American men greatly influenced our society. Mr. Andrew Young, Mr. Thurgood Marshall, and Mr. Jessie Owens are all prime examples of men who were essential to the growth and development of the African American race. These men have played a large role in breaking social constructs within our communities. They are prominent figures in history, and furthermore, members of Alpha Phi Alpha Fraternity, Incorporated. The majority of the men I…

As many of you probably haven’t heard of the Divine Nine which consist of 9 different African American fraternities and sorority organizations which has been a pivotal part of African American history and culture since the early 20th century. Which are the Alpha Phi Alpha Fraternity, Alpha Kappa Alpha Sorority, Kappa Alpha Psi Fraternity, Omega Psi Phi Fraternity, Delta Sigma Theta Sorority, Phi Beta Sorority, Sigma Gamma Rho Sorority, and Iota Phi Theta Fraternity. In the early 1900s, African…

The main composition of this group is religion being a church group. We all go to Antioch community church and consider ourselves either Christians or Jesus Followers. This was an intentional result from careful recruiting at Sunday service or by ways of socialization or assimilation once a person starts to attend the Lifegroup or Section. I know when I first started to attend Lifegroup; I was not a devoted Christian. I believed in God and Jesus, but practiced no rituals or norms associated with…

Alpha Males: Natural Born Leaders There are several movie characters that hold great standing, but then, they are fewer characters that possess a reputation that is erected on just moments that would reflect on how I feel about myself; Robert DeNiro is that person whose on-screen body language makes him a natural born leader, and the mannerisms help to boost his alpha male persona, which propels his characters to another level. Furthermore, he captures the personalities that he is projecting,…

were this way were before the war broke out. Before the war broke out there was balance between dark and light, we were a thriving pack of 34 wolves and growing but then the darkest pack in the forest the Demons took over our land killing all of our members including the alpha female, male, and the beta female now I’m the only alpha left in the pack, now 6 of us left, my beta Max, the protector Jordan, and the 3 omegas, Thunder, Winter, and Fall. My parents were the alphas before they were…

increasing in different career fields, which is why knowing how to correctly use technology is beneficial to professionals.

since the 1400 but did not become prevalent in black fraternities and sororities until Alpha Phi Alpha was founded in 1906 and Alpha Kappa Alpha in 1908. Then later on when the rest of the divine nine was founded. “ Kimbrough, Walter M. "Adults Influence Violent Hazing at Black Fraternities, Says HBCU President." BET.com. 18 Mar. 2014.
