Hi all, I have an array containing the following 3 elements: 
@array = ('>143B_HUMAN (P31946) 14-3-3 protein beta/alpha (Protein kin

For each element, I only want to extract the sequence of capital letters i.e. MERYSHIBDOCLDPKSD..... in each element. I have tried using a foreach loop to implement the substr function on each element, with no luck. Any help would be appreciated. Thanks
