PURPOSE: 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 acetylized carboxy (C) end by function of acetic anhydride vapor. ;CONSTITUTION: Amino acid at a ...

I have an amino acids string "MKGK" and I would like to convert it intoSMILESformat. I tried two approaches. First withPepSMIwhich gives me: N[C@@]([H])(CCSC)C(=O)N[C@@]([H])(CCCCN)C(=O)NCC(=O)N[C@@]([H])(CCCCN)C(=O)O Second, using ChemAxon Marvin'smolc...
RNA molecules can fold into intricate shapes that can provide an additional layer of control of gene expression beyond that of their sequence. In this Review, we discuss the current mechanistic understanding of structures in 5′ untranslated regions (UTRs) of eukaryotic mRNAs and the emerging metho...

How do we find the number of amino acids in a sequence? How many codons code for the amino acid arginine? How many tRNA types are in a human cell? Which two functional groups are always found in amino acids? If each nucleotide codes for a specific amino acid, how many different amino...
The Peptide Encoding Problem consists on Finding substrings of a genome encoding a given amino acid sequence. The genetic code describes the translation of an RNA 3-mer (codon) into one of 20 different amino acids. The first three circles, moving from the inside out, repr...
How many codons are needed to specify three amino acids? What is the stereochemistry of amino acids? How do we find the number of amino acids in a sequence? How many codons code for the amino acid arginine? What amino acid cannot be phosphorylated? A hypothetical gene 900 nucleotide long ...
to compare two genomes is to find the parts that match nearly perfectly. When that is done, we find that 2.4 billion of the base pairs of the human genome line up “nearly” perfectly with 2.4 billion of the base pairs of the chimp genome. As the 2005 paper on the draft sequence ...
I am using python to create a program that converts a set of DNA sequences into amino acid (protein) sequences. I then need to find a specific subsequence, and count the number of sequences in which this specific subsequence is present. This is the code I have s...
