Since the crystal structures of human paralogs of Artemis, CPSF-73 [71], Apollo and SNM1A (Unpublished structures; PDB codes: 3ZDK and 4B87) are available in the Protein Data Bank and the catalytic core of Artemis shares 32 and 26% sequence identity with those of Apollo and SNM1A, the structures in complex with zinc atoms can be used to build a homology model of Artemis.
In keeping with this hypothesis, an unpublished crystal structure of Crp-DNA-cAMP complex (RCSB: 3MZH) shows the same degree of bending observed for our PrfA complexes when using an intact DNA lacking breaks (Fig. S1A).
However, the binding of Fe3+ is so far backed only by its presence in an unpublished crystal structure (PDB ID 3bv6), and therefore its biochemical relevance will require a more extensive characterization.
Both CASP and CAPRI are blind prediction experiments that rely on the willingness of structural biologists to provide unpublished experimental structures as targets.
The published structures of MST3 with a variety of co-factors (ADP, adenine, ADP + Mn) [21], as well as other unpublished MST3 structures in the PDB (3CKW, 3CKX), were all also derived from MST3 constructs lacking the C-terminal WIF motif.
In contrast, our results showed that L-PAF-AH, which is again, highly similar to the α1-subunit of PAF-AH isoform I with respect to the primary amino acid sequences (Figure 1) and the simulated 3-D structure (unpublished data), could hydrolyze the 1-myristoyl-2- 4-nitrophenylsuccinyl -phosphatidylcholine (Table 1-myristoyl-2- 4-nitrophenylsuccinyl -phosphatidylcholine
When L-PAF-AH was firstly recognized by its deduced amino acid sequence [14] and simulated tertiary structure (unpublished data) similarity to the α1-subunit of the mammalian PAF-AH isoform I via the annotation of L. interrogans genome, its enzymatic activity was identified employing an artificial substrate used for assaying the serum enzyme [21].
In a preliminary study, we explored the application of NCD to two sheep populations, one that included multiple breeds [ 7] and another with known sire groups and a half-sib population structure (unpublished data).
To expand the substrate specificity of the extralong MnP6 maintaining its stability, two variants were prepared after comparing its recently solved crystal structure (unpublished) with those of P. ostreatus VP1 [ 17] and P. chrysosporium LiP-H8 [ 28].
A very recent study by (Brandl and Ibsen: The effects of institutional instability in collective bargaining: a long-term analysis of changing collective bargaining actors and structures, Unpublished) offers a preliminary investigation of this issue.
