Web services

Most data in GPCRdb is available programmatically via a REST API.

API reference

Each endpoint is described in the API reference.

Examples

Python 3 with requests

This is the recommended approach. Requires installation of the requests library.

import requests

# fetch a protein
url = 'https://gpcrdb.org/services/protein/adrb2_human/'
response = requests.get(url)
protein_data = response.json()
print(protein_data)
print(protein_data['sequence'])

# fetch an alignment
url = 'https://gpcrdb.org/services/alignment/protein/adrb1_human,adrb2_human,adrb3_human/TM3,TM5,TM6/'
response = requests.get(url)
alignment_data = response.json()
for protein, sequence in alignment_data.items():
    print(protein)
    print(sequence)

Python 3 with urllib

from urllib.request import urlopen
import json

# fetch a protein
url = 'https://gpcrdb.org/services/protein/adrb2_human/'
response = urlopen(url)
protein_data = json.loads(response.read().decode('utf-8'))
print(protein_data)
print(protein_data['sequence'])

# fetch an alignment
url = 'https://gpcrdb.org/services/alignment/protein/adrb1_human,adrb2_human,adrb3_human/TM3,TM5,TM6/'
response = urlopen(url)
alignment_data = json.loads(response.read().decode('utf-8'))
for protein, sequence in alignment_data.items():
    print(protein)
    print(sequence)

Python 2 with urllib2

from urllib2 import urlopen
import json

# fetch a protein
url = 'https://gpcrdb.org/services/protein/adrb2_human/'
response = urlopen(url)
protein_data = json.loads(response.read())
print protein_data
print protein_data['sequence']

# fetch an alignment
url = 'https://gpcrdb.org/services/alignment/protein/adrb1_human,adrb2_human,adrb3_human/TM3,TM5,TM6/'
response = urlopen(url)
alignment_data = json.loads(response.read())
for protein, sequence in alignment_data.iteritems():
    print protein
    print sequence
