Systems and methods to automatically de novo assemble a set of unordered read sequences into one or more, larger nucleotide sequences are presented. The method involves first creating two identical sets of the reads, dividing each read in both sets into smaller sorted mer sequences and then comparing the mers for each read in set 1 to the mers from each read in set 2 to exhaustively identify overlapping segments. Overlap information is used to construct a modified assembly string graph, traversal of which produces a sorted string graph layout file consisting of all the reads ordered left to right including their approximate starting offset position. The sorted string graph layout file is then processed by a novel multiple sequence alignment system that uses mer matches between all the overlapping reads at a given position to place matching individual bases from each read into columns from which an overall consensus sequence is determined.

The present invention is an accelerated conformational sampling method for predicting target peptide and protein structures comprising a process of determining energy minimized synthetic templates using a simple system for modeling individual molecular bonds within the subject peptide or protein. Use of these synthetic templates greatly reduces the computational resources necessary for optimally determining structural features of the target peptide or protein. The present invention also provides methods for rapid and efficient analysis of the effect of mutations on target peptides and proteins.

Protein structure prediction system

Systems and methods automatically identify a set of read sequences in one or more larger nucleotide sequences within a set of comparing sequences as a template. The sequences of each set are divided into smaller mer sequences and sorted to arrange the mer sequences in order, and the sets of mers originating from the read sequence set and the comparing sequence set are compared pairwise to determine matching regions between the sequences of the read sequence set and the sequences of the comparing set. The sorting of the sequence sets prior to the pairwise comparison reduces the amount of volatile memory required to assemble the read sequence set and also reduces the overall time to identify matches of the read sequence set in one or more larger nucleotide sequence databases.

A two-vessel continuous flow system in conjunction with low mutation reduced genome bacterial strains provides a platform for long term extended fermentations. Such systems require modification of standard fermentation devices such as probes, pumps and monitoring systems as well as improved procedures for feed delivery, culture monitoring and product harvesting methods. An optimized two-vessel system for producing large quantities of fermentation products from small volume, long duration continuous fermentations represents a significant improvement over existing fermentation strategies. Methods and compositions for long term continuous flow fermentation using a two vessel continuous culture fermentation apparatus are described.
