Hello Monks, I have a problem and I would greatly appreciate your wisdom to solve it. So, I am reading from a fasta file (containing protein seqeunces) while looping over and trying to print protein sequences. My problem is: When trying to print each protein sequence that I have in my hash, the sequences are broken down as follows: 
Protein sequence:STARTXXXXX
Protein Sequence: XXXXXXXXX
Protein sequence: XXXXXXEND

Question: How could I avoid this? Here is my script: 
use warnings;

my %database;
my $protein_id = "";
my $line = "";
my $datbase_filename="";
my $start=">DDB";
my $end="";
#input1: open the file containg the protein sequences.
print"Please enter the path to the fasta file of protein sequences \n"
+;

#put the file name into $filenam
$database_filename=<STDIN>;

#remove newline
chomp($database_filename);

#open the file containing protein sequences in fasta format
open(MYFILE1,"<$database_filename") or die "Unable to open $database_f
+ilename: $!\n";

while(<MYFILE1>) 

{    #remove newline
    chomp; 
    $line=$_;
    #print "Line i: $_\n"; #test
    
        if (($line=~m/^>DDB/) and
            ($line=~ m/to\s\d+$/))
            {
                $protein_id = $line;
                #print "protein ID: $protein_id\n";#test
            }
            
        else
            {
                $proteins{$protein_id} = $line;# associating the prote
+in sequence in my %proteins to its  ID
                
                print "sequence: $line\n";#test
                
            }
        
}
exit;

Many thanks in advance.
