Project Description

This is a library to evaluate an aminoacid sequence and determine an amphipathic index for each alpha helix or beta sheet.


If you want to use this library on any GNU/Linux or OSX system you just need to execute:

$ pip install noaaclass

If you want to collaborate with this library, you should download the github repository and execute:

$ make deploy


To test all the project you should use the command:

$ make test


This library can analyze an aminoacid sequence and gives a list of secondary structures with the respective index:

import amphipathic
resume = amphipathic.index('NLYIQWLKDGGPSSGRPPPS')
print resume

And the result should be:

    {'end': 2,
     'begin': 0,
     'type': u'c',
     'seq': 'nl',
     'amphipathic': {'index': 7.572935321054872e-05, 'mean': 2.6}},
    {'end': 5,
     'begin': 2,
     'type': u'e',
     'seq': 'yiq',
     'amphipathic': {'index': 1.4312912272216411, 'mean': 1.7299999999999998}},
    {'end': 18,
     'begin': 5,
     'type': u'c',
     'seq': 'wlkdggpssgrpp',
     'amphipathic': {'index': 0.002511560979331271, 'mean': -0.43}},
    {'end': 20,
     'begin': 18,
     'type': u'e',
     'seq': 'ps',
     'amphipathic': {'index': 1.6242872515167746, 'mean': -1.34}}

It also accept a nucleotide sequence to perform the same analysis:

import amphipathic
resume = amphipathic.index('cgcgtccttggagcaatgcagttcaagaccaagaatcgaattgaacctgt')
print resume

And the output:

    {'end': 12,
     'begin': 0,
     'type': u'c',
     'seq': 'rvlgamqfktkn',
     'amphipathic': {'index': 0.007560225956225585, 'mean': 0.7825000000000001}},
    {'end': 15,
     'begin': 12,
     'type': u'e',
     'seq': 'rie',
     'amphipathic': {'index': 1.6297837670649824, 'mean': 1.4599999999999997}},
    {'end': 16,
     'begin': 15,
     'type': u'c',
     'seq': 'p',
     'amphipathic': {'index': 0.0, 'mean': -2.23}}
