The enzyme cytidine deaminase catalyzes the conversion of cytidine to uridine. Cytidine deaminase catalyzes the reaction through an addition of water across the cytidine 3,4-bond, forming a tetrahedral intermediate followed by the elimination of NH3 to form the product uridine. This is like the addition-elimination mechanism that we studied for adenosine deaminase. Cytidine deaminase НО.

I. A protein, X, was Isolated from a pathogenlc mlcroorganism. The proteln Is a vlrulence factor whose path0genlclty lies In a heptapeptide of unknown sequence. After trypsin cleavage of the heptapeptide from protein X, the peptlde's compOsition and sequence was determined. The fOllowing were the results of the sequenclng process: 1. When the peptide was treated with dinitrofluorobenzene (DNFB), DNP-asp and a mixture of amino acids were produced. 2. When the same Intact peptide was treated with streptococcal protease, a pentapeptide of composition asp, asN, cys, gly and ser and 2 amlno acids were released. 3. When the heptapeptlde was also treated with hydrOxylamine HCI, a tripeptide and a tetrapeptide were obtained. The C-terminal amino acid of the tripeptide was asN. 1) What is the sequence of the heptapeptide if it is composed of cys, asp, lys, asN, gly and ser only? 2) What is the pl of the heptapeptide?
