npm ‘is’ Package Hijacked in Expanding Supply Chain Attack
The ongoing npm phishing campaign escalates as attackers hijack the popular 'is' package, embedding malware in multiple versions.
TLDR: This parser can be used to parse UniProt accession id and obtain related data from the UniProt web database.
To use:
python -m pip install uniprotparser
or
python3 -m pip install uniprotparser
With version 1.2.0, we have exposed to
and from
mapping parameters for UniProt API where you can indicate which database you want to map to and from.
from uniprotparser import get_from_fields, get_to_fields
#to get all available fields to map from
from_fields = get_from_fields()
print(from_fields)
#to get all available fields to map to
to_fields = get_to_fields()
print(to_fields)
These parameters can be passed to the parse
method of the UniprotParser
class as follow
from uniprotparser.betaparser import UniprotParser
parser = UniprotParser()
for p in parser.parse(ids=["P06493"], to_key="UniProtKB", from_key="UniProtKB_AC-ID"):
print(p)
With version 1.1.0, a simple CLI interface has been added to the package.
Usage: uniprotparser [OPTIONS]
Options:
-i, --input FILENAME Input file containing a list of accession ids
-o, --output FILENAME Output file
--help Show this message and exit.
With version 1.0.5, support for asyncio through aiohttp
has been added to betaparser
. Usage can be seen as follow
from uniprotparser.betaparser import UniprotParser
from io import StringIO
import asyncio
import pandas as pd
async def main():
example_acc_list = ["Q99490", "Q8NEJ0", "Q13322", "P05019", "P35568", "Q15323"]
parser = UniprotParser()
df = []
#Yield result for 500 accession ids at a time
async for r in parser.parse_async(ids=example_acc_list):
df.append(pd.read_csv(StringIO(r), sep="\t"))
#Check if there were more than one result and consolidate them into one dataframe
if len(df) > 0:
df = pd.concat(df, ignore_index=True)
else:
df = df[0]
asyncio.run(main())
With version 1.0.2, support for the new UniProt REST API have been added under betaparser
module of the package.
In order to utilize this new module, you can follow the example bellow
from uniprotparser.betaparser import UniprotParser
from io import StringIO
import pandas as pd
example_acc_list = ["Q99490", "Q8NEJ0", "Q13322", "P05019", "P35568", "Q15323"]
parser = UniprotParser()
df = []
#Yield result for 500 accession ids at a time
for r in parser.parse(ids=example_acc_list):
df.append(pd.read_csv(StringIO(r), sep="\t"))
#Check if there were more than one result and consolidate them into one dataframe
if len(df) > 0:
df = pd.concat(df, ignore_index=True)
else:
df = df[0]
To parse UniProt accession with legacy API
from uniprotparser.parser import UniprotSequence
protein_id = "seq|P06493|swiss"
acc_id = UniprotSequence(protein_id, parse_acc=True)
#Access ACCID
acc_id.accession
#Access isoform id
acc_id.isoform
To get additional data from UniProt online database
from uniprotparser.parser import UniprotParser
from io import StringIO
#Install pandas first to handle tabulated data
import pandas as pd
protein_accession = "P06493"
parser = UniprotParser([protein_accession])
#To get tabulated data
result = []
for i in parser.parse("tab"):
tab_data = pd.read_csv(i, sep="\t")
last_column_name = tab_data.columns[-1]
tab_data.rename(columns={last_column_name: "query"}, inplace=True)
result.append(tab_data)
fin = pd.concat(result, ignore_index=True)
#To get fasta sequence
with open("fasta_output.fasta", "wt") as fasta_output:
for i in parser.parse():
fasta_output.write(i)
