Identification
Name:L-Prolinylglycine
DescriptionProlinylglycine is a dipeptide. It is a proteolytic breakdown product of larger proteins. E. coli can use this dipeptide as a substrate for carbon/nitrogen metabolism and a source of proline. It is transported via DppA, which appears to be both a dipeptide transporter and a dipeptidase. Pro-Gly utilization does not require any of the three major proline transport systems. [PMID:1702779]

Enzymes

General function:
Involved in proteolysis
Specific function:
Aminopeptidase N is involved in the degradation of intracellular peptides generated by protein breakdown during normal growth as well as in response to nutrient starvation
Gene Name:
pepN
Uniprot ID:
P04825
Molecular weight:
98918
Reactions
Release of an N-terminal amino acid, Xaa-|-Yaa- from a peptide, amide or arylamide. Xaa is preferably Ala, but may be most amino acids including Pro (slow action). When a terminal hydrophobic residue is followed by a prolyl residue, the two may be released as an intact Xaa-Pro dipeptide.
General function:
Involved in hydrolase activity
Specific function:
Dipeptidase with broad substrate specificity. Requires dipeptide substrates with an unblocked N-terminus and the amino group in the alpha or beta position. Non-protein amino acids and proline are not accepted in the C-terminal position, whereas some dipeptide amides and formyl amino acids are hydrolyzed. Also shows cysteinylglycinase activity, which is sufficient for E.coli to utilize cysteinylglycine as a cysteine source
Gene Name:
pepD
Uniprot ID:
P15288
Molecular weight:
52915
Reactions
Hydrolysis of dipeptides, preferentially hydrophobic dipeptides including prolyl amino acids.
General function:

Gene Name:
pepB
Uniprot ID:
P37095
Molecular weight:

Reactions
Release of an N-terminal amino acid, Xaa, from a peptide or arylamide. Xaa is preferably Glu or Asp but may be other amino acids, including Leu, Met, His, Cys and Gln.
General function:
Involved in aminopeptidase activity
Specific function:
Presumably involved in the processing and regular turnover of intracellular proteins. Catalyzes the removal of unsubstituted N-terminal amino acids from various peptides. Required for plasmid ColE1 site-specific recombination but not in its aminopeptidase activity. Could act as a structural component of the putative nucleoprotein complex in which the Xer recombination reaction takes place
Gene Name:
pepA
Uniprot ID:
P68767
Molecular weight:
54879
Reactions
Release of an N-terminal amino acid, Xaa-|-Yaa-, in which Xaa is preferably Leu, but may be other amino acids including Pro although not Arg or Lys, and Yaa may be Pro. Amino acid amides and methyl esters are also readily hydrolyzed, but rates on arylamides are exceedingly low.
Release of an N-terminal amino acid, preferentially leucine, but not glutamic or aspartic acids.
