WebIt has 237 amino acid residues and four carbohydrate side chains with linkages at amino acid 45 (asparagine), 69 (serine), 70 (threonine), and 71 (serine). The N- terminal amino acid is isoleucine, and the C- terminal residue is proline. Its MW is 28,430, and it has isoelectric points from 6.8 to 7.2 because of its various isoforms. WebMining the emerging abundance of microbial genome sequences for hypotheses is an exciting prospect of "functional genomics". At the forefront of this effort, we compared the predictions of the complete Escherichia coli genomic sequence with the observed gene products by assessing 381 proteins for their mature N-termini, in vivo abundances, …
