Alignment positive

Here k is the alignment position, 8k(X, Y) = 1, if the pair XKis observed at position k and 0 otherwise. Nk is the number of unique pairs observed... 

Represent the probability of observing the 20 amino acids in a randomly aligned position where all the types of amino acid residues were observed at least once. These probabilities are used with the log-likelihood scoring scheme. 

Transverse alignment positioning jackscrews shall be provided for drive train components weighing more than 200 kg (450 lbs) to facilitate transverse horizontal adjustments. Axial alignment positioning jackscrews shall be... 

A minimum of four alignment positioning screws shall be provided for each drive train component that weighs more than 400 kg (900 lbs) to facilitate horizontal adjustment within the rabbeted fit. 

Va),"3 Bacillus megaterium (Bm),114 Thermophilic bacterium PS3 (PS3),"5 and bovine heart (mitochondria bom)"6 were aligned. Positions with identical amino acid residues in all ATPase are indicated by asterisks. 

Table 10.2 Wrapping comparison of PDB-reported kinases in complex with staurosporine at position aligned with Src dehydron Q250-E267 (DH, dehydron HB, well-wrapped hydrogen bond). The wrapping variant is predicted to bind only to the kinases that have a dehydron at the aligned position and the prediction is contrasted with the experimental screening of the wrapping variant of staurosporine...

The score (S) for an alignment is calculated by summing the scores for each aligned position and the scores for gaps. 

Build from structurally aligned positions in set of homologous proteins... 

Identify the SNP observed at alignment position 6 (query nucleotide number 10) in Fig. 3. There is an A/G SNP in many of thedatabase sequences.

When analyzing long sequences, first do a test run with only one of the methods to assess whether the orthologous regions were defined correctly (see Note 3). When a skew (a systematic shift in alignment positions over the whole region analyzed) is observed, it may be necessary to trim or extend one of the two sequences. 

Fig. 1. Multiple alignment of amino acid sequences of 38 Cu-Zn SODs The amino acid numbering scheme of bovine SOD, used as a reference, is at the top of the figure. Alignment positions in /S-strand conformation in the bovine structure are included in shaded boxes. Residues involved in subunit contacts in the dimeric form of bovine SOD are indicated by black boxes placed above the bovine sequence. The amino acids forming the upper rim of the electrostatic channel are denoted by empty boxes. Reprinted with permission from Ref. 347.
