Any regular expressions gurus here?

Thanks.

This is the python code that did it. I could not do it in one pass. There is no global flag for python for regex.

def trypsinize(proteins):



	p = re.compile(r'([K|R])([^P])'

	q = re.compile(r'([K|R])([^,P])'

		

	output = []

	for protein in proteins:

		name = protein[0]

		sequence = protein[1]

		a = p.sub(r'\1,\2',sequence)

		b = q.sub(r'\1,\2',a)

		output.append([name,b.split(','])

	return output
