Structure of neurolysin reveals a deep channel that limits substrate access.
C.K.Brown, K.Madauss, W.Lian, M.R.Beck, W.D.Tolbert, D.W.Rodgers.
The zinc metallopeptidase neurolysin is shown by x-ray crystallography to have large structural elements erected over the active site region that allow substrate access only through a deep narrow channel. This architecture accounts for specialization of this neuropeptidase to small bioactive peptide substrates without bulky secondary and tertiary structures. In addition, modeling studies indicate that the length of a substrate N-terminal to the site of hydrolysis is restricted to approximately 10 residues by the limited size of the active site cavity. Some structural elements of neurolysin, including a five-stranded beta-sheet and the two active site helices, are conserved with other metallopeptidases. The connecting loop regions of these elements, however, are much extended in neurolysin, and they, together with other open coil elements, line the active site cavity. These potentially flexible elements may account for the ability of the enzyme to cleave a variety of sequences.

Figure 3.
Fig. 3. Model of substrate peptide binding. A molecular surface representation of neurolysin sectioned to show the large cavity at the bottom of the active-site channel is shown with the 13-residue substrate neurotensin modeled as described in the text. The N terminus of neurotensin is at the top.
Figure 4.
Fig. 4. Sequence selectivity. (A) Aligned sequences for known neurolysin cleavage sites. The sites listed are, top to bottom, from the neuropeptides neurotensin, angiotensin II, bradykinin, dynorphin A (residues 1-8), dynorphin A (residues 1-17), a second site in dynorphin A (residues 1-17), luteninizing hormone-releasing hormone, substance P, and a second site in substance P (8, 35). Residue types are indicated by different colors (blue = basic, brown = aromatic, green = aliphatic, black = proline or glycine, red = polar), and the hydrolysis position is indicated by the vertical line. (B) Details of the active site and nearby disordered loop (light blue; residues 600-612). The zinc cofactor is shown in dark blue and the catalytic water in red. Some side chains from residues in the mobile loop and active site are shown.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
