Analysis of Sequence Composition


 

Keywords:  Analysis of sequence composition.


 



 


Caution!

This unit is under development. There is some contents here but it is incomplete and/or may change significantly: links may lead to nowhere, the contents is likely going to be rearranged, and objectives, deliverables etc. may be incomplete or missing. Do not work with this material until it is updated to "live" status.


 


Abstract

The most basic step of sequence analysis is to ask: what amino acids does a sequence contain.


 


This unit ...

Prerequisites

You need the following preparation before beginning this unit. If you are not familiar with this material from courses you took previously, you need to prepare yourself from other information sources:

  • Biomolecules: The molecules of life; nucleic acids and amino acids; the genetic code; protein folding; post-translational modifications and protein biochemistry; membrane proteins; biological function.

You need to complete the following units before beginning this one:


 


Objectives

This unit will ...

  • ... introduce ;
  • ... demonstrate ;
  • ... teach ;


 


Outcomes

After working through this unit you ...

  • ... can ;
  • ... are familar with ;
  • ... have begun to.


 


Deliverables

  • Time management: Before you begin, estimate how long it will take you to complete this unit. Then, record in your course journal: the number of hours you estimated, the number of hours you worked on the unit, and the amount of time that passed between start and completion of this unit.
  • Journal: Document your progress in your Course Journal. Some tasks may ask you to include specific items in your journal. Don't overlook these.
  • Insights: If you find something particularly noteworthy about this unit, make a note in your insights! page.


 


Evaluation

Evaluation: NA

This unit is not evaluated for course marks.

Task:


Task:

Local composition
  1. Find pepinfo under the PROTEIN COMPOSITION heading.
  2. Retrieve the MYSPE Mbp1 related sequence from your R database, e.g. with something like
    cat(db$protein[db$protein$name == "UMAG_1122"), "sequence"]
  3. Copy and paste the sequence into the input field.
  4. Run with default parameters.
  5. Scroll to the figures all the way at the bottom.
  6. Do the same in a separate window for yeast Mbp1.
  7. Try to compare ... (kind of hard without reference, overlay and expectation, isn't it?)


Task:

Global composition
  1. Find pepstats under the PROTEIN COMPOSITION heading.
  2. Paste the MYSPE Mbp1 sequence into the input field.
  3. Run with default parameters.
  4. Do the same in a separate window for yeast Mbp1.
  5. Try to compare ... are there significant and unexpected differences?

If in doubt, ask! If anything about this learning unit is not clear to you, do not proceed blindly but ask for clarification. Post your question on the course mailing list: others are likely to have similar problems. Or send an email to your instructor.
